1 Introduction

Undoubtedly one of the most important contributions of Federico Olóriz (Fig. 1) to the paleontology of Jurassic ammonites is in the systematic paleontological aspect of the group. In his doctoral thesis (Olóriz, 1978) he proposed as new seven genera, two subgenera, 42 species and four subspecies, in addition to thirteen amendments at the family, subfamily and 7 on generic level. The present work compiles these contributions, as well as other proposals published by him and other authors (Olóriz & Tavera, 1979a, b; Olóriz & Schairer, 1983; Olóriz et al., 1985; Olóriz & Westermann, 1998; Olóriz & Villaseñor, 1999; Villaseñor & Olóriz, 2009; Villaseñor et al., 2003; Olóriz & Villaseñor, 2006; López-Palomino et al., 2006; Moliner & Olóriz, 2010; Villaseñor et al., 2015; Villaseñor & Olóriz, 2018; Olóriz & Villaseñor 2018; Villaseñor & Olóriz, 2019, 2020), regarding the creation of different taxa.

The impact of his extensive professional career is reflected in the dedication of several taxa in his honor (El Kadiri, 1992; Fözy, 1988; Mitta, 2011; Moliner & Olóriz, 2009; Sarti, 1993; Tavera, 1985), being worthy of the creation of genera and/or species.

The taxa proposed by the author and those dedicated to him are presented in chronological order of publication. Its taxonomic classification, figures, the original diagnosis of the genus and/or species translated when they are in other language than English, holotype, type locality and the assigned age are included. Also, when it was possible, comments on the official taxonomical status are given as well as webpage link.

2 Contributions of Federico Olóriz in his doctoral thesis (Olóriz, 1978)

  • Family Haploceratidae Zittel, 1884 sensu Ziegler, 1974

  • Subfamily Streblitinae Spath, 1925 sensu Ziegler, 1974

  • Genus Metastreblites Olóriz, 1978

  • Type species Metastreblites ellypticus Olóriz, 1978

Original diagnosis: "Streblites" in which the ratio between the maximum diameter contemplated at the beginning of the VR flattening and its perpendicular exceeds the value 1.4: W = 1.40–1.60. In the phragmocone, the ornamentation is similar to that of Streblites; the BCH is marked by a sudden narrowing of the coilling, with the development of lateral folds that occupy the external half of the flank. Next, new widening of the whorl and flattening of VR, now with a weak middle carina. In the second half of the BCH, the VR can be smooth and convex or present a groove. The peristome is simple and sinuous and the suture line, although poorly preserved, develops 4 or 5 auxiliary lobes on the flank, where the depth of the lateral lobe l stands out. Due to their oval shape, these shells are reminiscent of those of Semiformiceras semiforme (Oppel) (translated from Olóriz, 1978, p. 55).

  • Metastreblites ellypticus Olóriz, 1978 (pl. 2, fig. la, b and 2, scheme p. 54, 77)

Holotype: F.G15.7.13

Original diagnosis: Small elliptical shell, involute, oval section with wide and smooth VR. The ornamentation is like "tenuilobatus" in IW, but, after beginning the BCH, a narrowing of the whorl occurs that coincides with the development of lateral folds. Peristome simple and sinuous. The suture line poorly preserved, shows 4 or 5 accessory lobes and considerable development of the lateral lobe (translated from Olóriz, 1978, p. 55).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Kimmeridgian (Strombecki Zone—Lower part of Divisum Zone).

Original diagnosis: Elliptical shell with a small umbilucus, oval section and unequally acute depending on the stage considered. The ornamentation is not preserved on the phragmocone; then narrowing of the whorl and development of lateral folds; later, new widening of the whorl, now with a ventral groove. Peristome simple and sinuous. The suture line has 4 or 5 auxiliary lobes and great development of the lateral L (translated from Olóriz, 1978, p. 56).

Holotype: F.PR.II.213

Original diagnosis: Small size, large umbilicus, the section evolves from square to oval. VR more or less wide and covered or not by ribs depending on the stage. The ornamentation, in increasing diameters, responds to three stages: "perisphinctoid", "simoceroid" and "lytoceroid". The most characteristic elements of the suture line are the external and lateral lobes (of different width) as well as a wide external saddle (translated from Olóriz, 1978, p. 238).

  • Hybonoticeras (Hybopeltoceras) linaresi Olóriz, 1978 (pl. 29, fig. 2a, b. pl. 30, fig. la, b y 2, scheme p. 369, 370)

Holotype: F.G.17.19.2

Original diagnosis: Small to medium size, evolute, hexagonal section with groove over the VR. The carinae appear coarse and slightly crenulated in IW. In the last whorl of the phragmocone smooth and later they lose relief with a tendency to fade. The ornamentation is of simple and strong ribs with three tuberculiform points: in the UB or its vicinity, EB and VR. No data on the peristome. The suture line is extraordinarily simple with only two umbilical lobes; the saddles are wide, blunt, and not very deeply subdivided into two.

IW with more or less dense, bifurcated and polygyrated ribs with RES. In EW the ribs are spaced, the primaries are reinforced, and the divisions are complicated, appearing diversipartite-fasciculated with RES. It never really develops virgatostoma ribbing. In IW, constrictions can be frequent (translated from Olóriz, 1978, p. 410).

Original diagnosis: Small (?), evolute, depressed section. Bifurcated and simple ribs in IW. EW with reinforced and laterally projected primaries, as well as numerous secondaries (?), virgatostomes (?), polygyrates (?) and RES. No data on the peristome. Not very complex suture line with 4 broad saddles and 3–4 lobes on the flank. Among the lobes, lateral 1, trifid, lateral 2 broad, bifid and shallow (translated from Olóriz, 1978, p. 421).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Kimmeridgian (Strombecki Zone—Divisum Zone (Uhlandi Subzone)).

  • Genus Crussoliceras Énay 1960 amend. Olóriz, 1978

  • Type species Ammonites crussoliensis Fontannes in Dumortier y Fontannes, 1876

Original diagnosis amend: Crussoliceras is considered as a form of small to large size, strongly spaced ribbing in EW (intercostal space = 3 ribs), with bifurcated divisions, generally high, more or less proverse, and some RES. Infrequent trifurcations. There are rims of strong relief and oblique and deep constrictions. The section ranges from subrounded to oval. In small forms—less typical—the peristome is pedunculated; has not been observed in large-sized forms (translated from Olóriz, 1978, p. 426).

  • "Crussoliceras" postdivisum Olóriz, 1978 (pl. 34, Fig. 4a, b, scheme p. 431)

Holotype: F.G.17.20.12

Original diagnosis: Small size, evolute, subrounded to oval section. Bifurcate ribbing with some simple intercalated (?). Zig-zags can be seen along the ventral course of the secondary ribs. There are deep constrictions bordered by prominent rims. Peristome with lateral expansions. No data on suture line (translated from Olóriz, 1978, p. 429).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Tithonian (Verruciferum Zone).

  • Genus Biplisphinctes Olóriz, 1978

  • Type species Perisphinctes cimbricus Neumayr, 1873

Original diagnosis: Small shells, very evolute, with a shallow umbilucus with vertical UW and rounded UB. The sections are more or less subrounded—depressed in IW, gradually high, in EW, subrounded—quadratic or oval, in which the W/H ratio is close to l. The VR wide, slightly convex and covered by the ER. Throughout ontogeny, the growth of the whorls in W and H is very uniform, so that a fairly pronounced tubular appearance is achieved. The ornamentation consists of bifurcated ribs at certainly external points, sometimes almost marginal, between which a variable, but never excessive, number of simple ribs. No RES or polygyrated divisions or other more complex types have been observed. In general, the ornamentation can be more or less proverse and the secondary ones, always short, are unevenly projected towards the aperture and sometimes almost radial. It is not strange to observe zig-zag ribbing on the VR, a product of the asymmetrical, very localized character of ER. There are wide and oblique constrictions that interest then ribbing to a different degree, depending on the case. Pedunculate peristome. The BCH can occupy almost a complete whorl (translated from Olóriz, 1978, p. 438).

Age: Upper Kimmerridgian ("compsum" Zone-Beckeri Zone boundary)-lower Tithonian (Verruciferum Zone).

  • Biplisphinctes spathi Olóriz, 1978 (pl. 40, fig. 2 and 8, scheme p. 446)

Holotype: F.G.15.14.17

Original diagnosis: Small size, evolute, somewhat depressed subsquare section. Bifurcated ribbing according to fairly external divisions; there are simple intercaleted ribs in a small number. No data on suture line. Pedunculate peristome (translated from Olóriz, 1978, p. 441).

Type locality: Sierra Gorda (Granada), Spain.

Age: Upper Kimmeridgian ("Compsum " Zone-upper part (?) Beckeri Zone).

  • Biplisphinctes tithoni Olóriz, 1978 (pl. 40, fig. l, scheme p. 446)

Holotype: F.G.3.28.1

Original diagnosis: Small size, evolute, somewhat depressed subsquare section. Costulation bifurcated according to fairly external divisions; There are simple ribs interspersed in a small number. No data on suture line. Pedunculate peristome (translated from Olóriz, 1978, p. 444).

  • Genus Torquatisphinctes Spath, 1924 amend. Olóriz, 1978

  • Type species Ammonites torquatus Sowerby, 1840.

Original diagnosis amend: Small size, wide but variable umbilucus, medium depth, with vertical UW and rounded UB. The section is subrounded in IW, it grows in height towards the EW, and the flanks may be unequally flattened, so that in the EW the transverse section appears more or less subrounded-subovate or subsquare-subrectangular with wide VR. Designs of the T. guembeliregularis Zeiss type is not frequent. The ornamentation is quite regular and consists of bifurcate and simple elements. The bifurcations are made between 1/2 and 2/3 H, and due to the arrangement of the secondary ribs, the division points are not highlighted; The frequency of simple ribs is not very great and their number, with exceptions (ruber Spath, alterneplicatus Waagen, sp.2), does not exceed one per interval. Sometimes in VR, it is possible to observe "zig-zag" devices due to sporadic asymmetry in the ER. I have not confirmed the existence of RES, but its presence can be admitted, isolated, in relation to the aforementioned asymmetry of the secondary ribs. There are oblique constrictions, of different development and that alter, to a different degree, the rhythm of the ornamentation. Trifurcations, polygyrated divisions or other more complex types do not develop. At least in some cases (?) the peristome is pedunculated. The BCH can reach a practically complete whorl (translated from Olóriz, 1978, p. 448).

  • Torquatisphinctes laxus Olóriz, 1978 (pl. 40, Fig. 4, scheme p. 460)

Holotype: F.G.12.20.3

Original diagnosis: Small size, very evolute, sub rectangular-oval section with maximum thickness in the UB. Bifurcate and simple ribs. No data on the peristome and suture line. There are constrictions (translated from Olóriz, 1978, p. 454).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Tithonian (Hybonotum Zone).

  • Torquatisphinetes transiens Olóriz, 1978 (pl. 40, fig. 3, scheme p. 460)

Holotype: F.G.9.9.9

Original diagnosis: Small size, evolute, rectangular-oval section with maximum thickness near the UB. Bifurcate ribs with a variable number of intercalated simple ribs. Inconspicuous constrictions. No data on opening and suture line (translated from Olóriz, 1978, p. 456).

Type locality: Sierra Gorda (Granada), Spain.

Age: Upper Kimmeridgian, (lower part) Beckeri Zone.

  • Genus Discosphinctoides Olóriz, 1978

  • Type species Perisphinctes roubyanus Fontannes, 1879

Original diagnosis: Small size, variable involution, oval section with flattened, or somewhat convex, flanks, and more or less converging towards VR. Simple ribs based on elements fundamentally bifurcated at 2/3 H, sometimes with slightly deeper divisions; a small number of simple ribs may also be intercaleted and at the end of the BCH, polygyrated and perhaps RES. At least in some cases pedunculated peristoma, in others, unknown. Constrictions are not very frequent (translated from Olóriz, 1978, p. 481).

Age: Upper Kimmeridgian (Cavouri Zone–Beckeri Zone).

  • Genus Subplanites Spath, 1925 amend. Olóriz, 1978

  • Type species Perisphinctes (Virgatosphinctes) reisi Schneid, 1914.

Original diagnosis: Small to medium size, evolute, subtrapezial-oval section, more or less tall, wide, and with the maximum thickness located in the periumbilical area; the UW is usually steep, the UB rounded, and the VR broad and not excessively convex. In phragmocone, the ribs are generally dense and thin, although there are forms in which the spacing is greater and the ribs somewhat stronger; in all cases, considering the morphology, the angle that separates the secondary ribs has a small or medium amplitude, the ribs are rigid, proverse, and the ER are arranged in continuation of the primary ones from which they come. In the BCH, quite rigid polygyrated divisions begin to be intercaleted, until they end up being dominant; only towards the end of the shell can some sinuosity be observed, but the vigor of the ornamentation gives it an unmistakable style. Although with different development, there are RES and constrictions. The BCH occupies between 3/4 and 4/4 of the last whorl. Pedunculate peristome (translated from Olóriz, 1978, p. 499).

Original diagnosis: Small size, medium involution, oval section. Bifurcated ribs with a predominance of polygyrated ones in the BCH. Very rare simple ribs and scarce RES. No data on the peristome and suture line. The BCH occupies at least one practically complete whorl (translated from Olóriz, 1978, p. 502).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Tithonian (Hybonotum Zone).

  • Genus Subplanitoides Zeiss, 1968 amend. Olóriz, 1978

  • Type species Usseliceras (Subplanitotdes) waltheri Zeiss, 1968

Original diagnosis amend: Small size, pedunculated peristome. IW with bifurcated costulation; polygyrated and ataxioceratoid divisions may appear in EW. Variable involution, superficial umbilicus with rounded UB and, together with the UW, unevenly developed. The section ranges from oval-narrow to sub-rectangular; on VR, a more or less pronounced discontinuity may or may not develop. In the ornamentation, the inflection at the level of the division points is very characteristic, which are between 1/2 and 2/3 H. There are never complex divisions in IW. The angle that separates the secondary ribs, in the most typical forms, is no wider than the thickness of a rib. Simple ribs and constrictions are not excessively common. In general, the ornamentation is delicate compared to other lower Tithonian microconchs and the ER, at most, draw a gentle convexity on the VR. Ataxioceratoid divisions are exceptional (translated from Olóriz, 1978, p. 526).

  • Subplanitoides zeissi Olóriz, 1978 (pl. 50, fig. 5, scheme p. 541)

Holotype: F.G.10.12.19

Original diagnosis: Small size, evolute, rectangular-oval section. Ribs basically bifurcated, except for some simple ones in relation to the constrictions (7) or the opening. Possible strangulations are shallow and parallel to the ribs. Pedunculate peristome. No data on suture line (translated from Olóriz, 1978, p. 532).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Tithonian (Verruciferum Zone).

  • Genus Parapallasiceras Spath, 1925 amend. Olóriz, 1978

  • Type species Berriasella (Aulacosphinctes ?) praecox Schneid, 1915

Original diagnosis amend: Small-sized microconch, involute, with whorls of subrounded to subtrapezial-oval section with a siphonal groove or discontinuity, more or less developed and durable. Ornamentation strong, rigid or somewhat flexuous, radial or slightly proverse, basically bifurcated in the phragmocone and spaced in the IW; in the BCH, RES and polygyrated divisions can be intercalated. No special reinforcement of the ribs is observed in the UB. There are strong, deep and unevenly constrictions parallel to the ribs. As the diameter increases, a notable decrease in density is not observed. In cases where it has been possible to verify, the peristome is pedunculated. A polyphyletic character is admitted for this form (translated from Olóriz, 1978, p. 545).

Type locality: Sierra Alta Coloma (Granada-Jaén), Spain.

Age: Lower Tithonian (condensed bed Verruciferum Zone-Richteri Zone).

  • Genus Richteria Olóriz, 1978

  • Type species Ammonites richteri Oppel in Zittel, 1868

Original diagnosis: Small size, generally evolute, although there is no shortage of species in which H > U; the umbilicus is not deep and is limited by a UW with rounded edges, sometimes strongly inclined. The section ranges from subrectangular to oval, the flanks are gently convex or flattened and the maximum thickness is usually in relation to the vicinity of the UB. The W/H ratio is variable and decreases as the diameter increases. The ornamentation is rigid, proverse and bifurcated in IW, in BCH it can remain unchanged or evolve towards finer and sinuous ribs, with more complex divisions, and even develop a certain tendency to weaken. At all times, the ribs cross an unequally wide VR forming a fairly pronounced "chevron" (~ = 40°–62°). There may be some simple but not ataxioceratoid ribs; RES are rare. The peristome is unknown. The suture line, judging by the one provided in Zittel (1868, pl. 20/9d), is not very complex, presents broad, poorly carved elements, and bears a certain analogy with that of “P.” calisto and “P.” lorioli (cf. Siedmiradzki, 1898, p. 203, fig. 36). The BCH occupies at least 3/4 of a whorl (translated from Olóriz, 1978, p. 594).

Comments: A new name for the type species Ammonites richteri Oppel in Zittel, 1868, was proposed previously by Avram (1974), as Richterella, following the ICZN (2000) Art. 33.2.3 the new genus proposed by Olóriz (1978) is an objective synonymy.

Age: Lower Tithonian (end of Verruciferum Zone ?-Richteri Zone).

  • Richteria striata Olóriz, 1978 (pl. 51. fig. 4, scheme p. 603)

Holotype: F.AC.1.201

Original diagnosis: Small size, involute, oval section. Basically bifurcated costulation. There are some simple ribs and a polygyrated division has certainly been observed. Rare and poorly developed constrictions. No data on the peristome and suture line (translated from Olóriz, 1978, p. 599).

Type locality: Sierra Alta Coloma (Granada-Jaén), Spain.

Age: Lower Tithonian (end of Verruciferum Zone ?-Richteri Zone).

  • Genus Lemencia Donze-Enay, 1961 amend. Olóriz, 1978.

  • Type species Lemencia pseudorichteri Donze-Enay, 1961

Diagnosis amend: Variable growth in height (not necessarily rapid), so its variation may be weak. The VR may not be as narrow as Donze-Enay suggests, and I certainly have not observed a single case of "pinched" VR (pincée). Most likely this type of VR is linked to "L." praerichteri Donze-Enay, Richteria in this report. There are some species that keep their flanks practically parallel in the BCH and, therefore, the section does not appear pointed.—The statement of "a veritable sillón siphonal” may be too categorical, so that there are species, some referred to in Schneid, 1915, which instead develop a flattening or gentle weakening of the ER in an area that appears somewhat tabulated. Forms are excluded, such as praerichteri, in which the ER form a very pronounced "chevron", there is no trace of ventral continuity and, on the contrary, there are strong on phragmocone and part of BCH. The ribs do not necessarily appear more numerous and flexuous in the BCH and even in the vicinity of the peristome. Apart from the new species described here, this fact can be observed in certain forms of Schneid, 1914 and 1915. Of less importance is the reference to "fascieux virgatostomes". since these are actually polygyrated divisions, more or less flexuous. Polyphyletic origin since the hypothesis of Zeiss (1968, p.103) in which it is considered a Sublithacoceras microconch does not seem sufficiently proven either. (translated from Olóriz, 1978, p. 605).

  • Lemencia pseudopergrata Olóriz, 1978 (pl. 52, fig. 5)

Holotype: F.A.2a.7.19

Original diagnosis: Small size, involute, rectangular section with convex VR. Costulation bifurcated at 2/3 H. Constrictions poorly developed. No data on suture line. The BCH occupies between 3/4 and 4/4 of a whorl. Pedunculate peristome (translated from Olóriz, 1978, p. 616).

Type locality: Sierra Arana (Granada) Spain.

Age: Lower Tithonian (upper part Admirandum/Biruncinatum Zone—Burckhardticeras Zone).

  • Lemencia strangulata Olóriz, 1978 (pl. 52, fig. 15. scheme p. 623)

Holotype: F.A.2a.9.77.

Original diagnosis: Small size, evolute, rectangular section with gently convex VR. In the phragrmocone, bifurcate ribs; in the BCH some polygyrated divisions are intercalated and strong constrictions develop. No data on the peristome and suture line. The BCH occupies at least 3/4 of the whorl (translated from Olóriz, 1978, p. 619).

Type locality: Sierra Arana (Granada), Spain.

Age: Lower Tithonian (upper part Admirandum/Biruncinatum Zone—Burckhardticeras Zone)

  • Lemencia interposita Olóriz, 1978 (pl. 52, fig. 9, scheme p. 623)

Holotype: F.PR.5.30

Original diagnosis: Small size, evolvute, oval section. In the phragnocone the costulation is bifurcated; in BCH, frequent RES appear. Underdeveloped constrictions. No data on suture line and peristome (translated from Olóriz, 1978, p. 620).

Type locality: Sierra Alta de Coloma (Jaén), Spain.

Age: Lower Tithonian (Burckhardticeras Zone).

  • Genus Burckhardticeras Olóriz, 1978

  • Type species Himalayites (Micracanthoceras) peroni Roman, 1936

Original diagnosis: Small size (55 mm?), evolute, more or less depressed subrounded section and pedunculated peristome. Ornamentation of bifurcate and acute ribs with excavated intercostal spaces. There are some simple elements and, in certain varieties, trifurcated, polygyrated and RES divisions. The density usually remains uniform, although there are varieties that have comparatively higher density in the nucleus. The coating is weak but variable, so that the bifurcations of the innermost whorls may or may not be observed. The constrictions do not reach considerable development and linked to them are simple ribs or false polygyrated divisions. The VR is flattened and wide in the most typical forms so that in its midline it presents, to varying degrees, a tendency towards siphonal discontinuity, rather weakening or notching, but never a well-excavated groove that interrupts the ribbing. In some forms, facilitated by the acute nature of the costulation, a certain inclination towards “lamelliform tuberculation” is observed in VR on the primary ribs. At no time are tubercles s. str. The suture line, although preserved, does not facilitate its study due to the deterioration of its elements (translated from Olóriz, 1978, p. 624).

Holotype: Román (1936, p. 24, pl. 4/21–13)

Age: Lower Tithonian (Burckhardticeras Zone). Some records in the lowermost part of upper Tithonian.

Comments: The same name of Burckhardticeras was proposed previously by Flores-López (1967), for an arnioceratid ammonite, a wide discussion for the status on Burckhardticeras was given by (Villaseñor & Olóriz, 2024). Zoobank officially considerers an accepted genus https://zoobank.org/NomenclaturalActs/1de6e2cc-7c2a-4cc6-bcff-49896743e329.

  • Family Berriasellidae Spath, 1922.

  • Subfamily Himalayitinae Spath, 1925.

  • Genus Aulacosphinctes Uhlig, 1910 amend. Olóriz, 1978

  • Type species Ammonites moerickeanus Oppel, 1863

Diagnosis amend: Small size, evolute with subrounded, oval or subquadrate whorls that support a well-developed groove in the VR. The ornamentation is variable, so that types with a more or less perisphinctoid appearance can develop, while in other cases it results in a marked himalayan aspect. There are constrictions. The ribs are basically bifurcated with simple intercalated elements, and sometimes a smaller proportion of polygyrated divisions. Pedunculate peristome. The BCH occupies approximately one complete whorl. Tubercles do not develop (translated from Olóriz, 1978, p. 631).

  • Aulacosphinctes quadri Olóriz, 1978 (pl. 53, fig. 15a, b, scheme p. 630)

Holotype: F.PR.2.274

Original diagnosis: Small size, evolute, quadratic, depressed section, with a wide sulcus on VR. Bifurcated, rigid, radial ribs. Rare simple ribs. No data on the suture line and peristome. The BCH occupies a practically complete whorl (translated from Olóriz, 1978, p. 638).

Type locality: Sierra de Alta Coloma (Granada-Jaén) Spain.

Age: Lower Tithonian (Burckhardticeras Zone).

  • Aulacosphinctes trifidus Olóriz, 1978 (pl. 53, fig. 14a, b, scheme p.630)

Holotype: F.GA.7.18.7

Original diagnosis: Small size, evolute, oval section with narrow VR and run through a groove. bifurcated ribbing; rare simple ribs and, at the end, development of polygyrated divisions. No data of peristome and suture line” (translated from Olóriz, 1978, p. 640).

Type locality: Sierra Gorda (Granada), Spain.

Age: Lower Tithonian—upper Tithonian boundary.

  • Aulacosphinctes berriaselliformis Olóriz, 1978 (pl. 53, fig. 16a, b, scheme p. 630)

Holotype: F.PR.2.55

Original diagnosis: Small size, evolute, oval section with VR tabulated and traversed by a groove that weakens towards the end of the last whorl. Ribs bifurcated, few simple, and in the second half of the CH intercalated polygyrated divisions. No data on aperture and peristome. The BCH occupies a practically complete whorl (translated from Olóriz, 1978, p. 641).

Type locality: Sierra de Alta Coloma (Granada-Jaén) Spain.

Age: Lower Tithonian (lower part of Burckhardticeras Zone).

  • Genus Djurjuriceras Roman, 1936 amend. Olóriz, 1978

  • Type species Djurjuriceras djurjurense Roman, 1936

Diagnosis amend: Small to medium size, evolute, subsquare-subrounded and more or less depressed section. The VR is wide, flattened, and sometimes tends to develop a slightly depressed middle area, or even a narrow and not very pronounced discontinuity. In the phragmocone, the ornamentation consists of regularly bifurcate ribs (perhaps there may be some simple element); in the second half of the BCH and with different development, a change in ornamentation occurs so that the intercostal spaces become very wide ("wide annular constrictions" of Fallot-Thermier) and are limited by simple ribs arranged in pairs. It is not unusual to find some RES related to these wide intercostal spaces or in the final part of the phragmocone, due to the asymmetry that can sporadically be observed in the ribbing. Constrictions are poorly developed; the BCH occupies approximately one whorl, and the suture line does not present any particularly prominent features. No data on the type of peristome. Without tubercles (translated from Olóriz, 1978, p. 646).

  • Djurjuriceras armonicus Olóriz, 1978 (pl. 53, fig. 4, scheme p. 630)

Holotype: F.PR.5.1

Original diagnosis: Small size, evolute, subrounded-depressed section. Ribbing basically bifurcated at the phragmocone; at the end of the BCH, the UR are spaced, and wide intercostal spaces develop, separated by simple ribs of sharp relief. No data on the peristome. The suture line appears to develop broad, bifid saddle and a trifid L1″ (translated from Olóriz, 1978, p. 648).

Type locality: Sierra de Alta Coloma (Granada-Jaén), Spain.

Age: Lower Tithonian (Burckhardticeras Zone).

3 Taxonomic contribution by Olóriz and other authors

In the next section are presented the taxonomic contributions of Federico Olóriz and other authors, in chonological order.

3.1 Contribution from Olóriz & Tavera (1979a)

  • Family Simoceratidae Spath, 1924

  • Subfamily Simoceratinae Spath, 1924

  • Genus Simospiticeras Olóriz & Tavera, 1979a

Original diagnosis: The most outstanding distinctive character is the development of bulliform periumbilical tuberculation while the ventral tuberculation is acute or crestiform and occupies the mid-siphonal line. They are small-medium sized shells (80–90 mm), with a wide and slightly depressed umbilicus. The spiral has a subrounded-oval section in IW and an ogival section in EW (especially in BCH). There are apparent, wide, curved and proverse constrictions. The ribbing is thin and with little relief in the VR, especially in the IW of the phragmocone. No data on the peristome. The suture line is quite simple and its broad elements present superficial accessory lobulations. Derivatio nominis: alludes to its morphology intermediate between Simoceratinos and Spiticeratinos (translated from Olóriz & Tavera, 1979a, p. 183)

  • Simospiticeras lojense Olóriz & Tavera, 1979a (pl. 1, fig. 1)

Holotype: Y.G. 77. X.2, by monotype

Original diagnosis: The same of the genus.

Type locallity: Sierra Gorda, Sierra de Gaena—Carcabuey (Granada, Spain)

Age: Lower part of upper Tithonian.

  • Simospiticeras cristatus Olóriz & Tavera, 1979a (pl. 1, fig. 2)

Holotype: W.Ga.20.18 by monotype

Original diagnosis: Not original diagnosis provided by the authors.

Type locallity: Sierra de Gaena—Carcabuey (Granada, Spain)

Age: Lower part of upper Tithonian.

3.2 Contribution from Olóriz & Tavera (1979b)

  • Family Simoceratidae Spath, 1924

  • Subfamily Simoceratinae Spath, 1924

  • Genus Simoceras Zittel, 1870

  • Subgenus Cordubiceras Olóriz & Tavera, 1979b

  • Type species Simoceras (Cordubiceras) geminatun Olóriz & Tavera, 1979b

Original diagnosis: Shells of small-medium size (maximum observed 100 mm) with a wide and shallow umbilicus. Spiral taller than wide, with maximum thickness close to the umbilical edge. In the ornamentation there is always a final stage of geminate ribs (last whorl) that serves to establish the subgenre. This characteristic development will be preceded, depending on the case, by phragmoconus of the “Simoceras” type or close to “Lytogyroceras”. The suture line responds to the Simoceratin model with wide and not excessively lobed elements. Perhaps it is worth noting that the siphonal lobe may have a significantly lower depth in the type species. (translated Olóriz & Tavera, 1979b, p. 3–4).

Comments: It is word to mention that Enay & Geyssant (1975) and later Geyssant (1979) propose the genus Baeticoceras, for specimens collected in Spain, later Tavera (1985) considered this genus as a junior synonym of Cordubiceras and elevated the subgenus as a genus.

  • Simoceras (Cordubiceras) geminatun Olóriz & Tavera, 1979b (pl. 1/1, 2, fig. 1)

Holotype: T.GA.6b.1.1

3.3 Contribution from Olóriz and Schairer (1983)

  • Family Haploceratidae Zittel, 1884

  • Subfamily Taramelliceratinae Spath, 1928

  • Genus Barthelia Olóriz & Schairer, 1983

Original diagnosis: A genus of Taramelliceratinae of small size, keeled, with a narrow umbilicus. The ribbed surface shows variations from recti- to rursiradiate ribs, which are mostly simple with long intercalatories and some biplicate. The last whorl is excentrically coiled and has numerous kinks. The aperture is narrow with a hook-shaped process in the umbilicus area, and small projections on the flanks and ventral region. The suture, as far as it is identifiable, shows similarities to those of Taramelliceras flexispinatum (Oppel) and Popanites paturattensis (Greppin) (translated from Olóriz & Scharier, 1983, p. 577).

  • Barthelia subbetica Olóriz & Schairer, 1983 (fig. 1, 2, 3a)

Holotype: Specimen in fig. 1, 1–4.

Original diagnosis: Not provided by the authors but should be the same for the genus.

Type locality: Sierra Quipar (Murcia), Betic Cordilleras, Subbetic Zone, Spain.

Age: Upper Oxfordian, (Bimammatum Zone).

3.4 Contribution from Olóriz et al. (1985)

  • Family Perisphinctidae Steinmann in Steinmann & Doderlein, 1890

  • Subrfamiie Ataxioceratinae Buckman, 1921

Holotype: Specimen in pl. 1, figs. 1–3; pl. 2, figs. 1, 2

Original diagnosis: Medium-sized, moderately evolute species of the genus Crussoliceras Enay with numerous polygyrate ribs starting from a relatively small diameter. The anterior ribs of each rib unit are usually clearly prorsiradiate. The whorl section is initially wider than high and later becomes subtrapezoidal to subsquare.

3.14 Contributions from Villaseñor & Olóriz (2019, 2020)

  • Burckhardtieia Villaseñor & Olóriz, 2019, 2020

  • Type species Hoplites mexicanus Aguilera, 1895 (in Del Castillo & Aguilera, 1895)

Holotype: IGM5

Original diagnosis: “Planulate to discoid shells. Coiling degree changing progressively from colubrinoid nuclei to moderately and, lesser common, widely umbilicate adults. Coiling degree stability higher in shells greater than 60 mm. Whorl-section progressively higher during growth, with an early, comparatively accelerated change to rather flattened flanks, and slightly rounded to tabulate venter. Occasional occurrence of small, local protuberances on the innermost whorls, just after a short initial stage of smooth-shell nuclei, and before development of the regular ribbing, as well as on the points of furcations short after the first apparition of ribs, but their occurrence is brief and belongs to an early phase of growth showing instability of phenotype traits. Typical scultpture is made of mainly bifurcate ribs on the inner and intermediate whorls, with possible addition of polygyrate to subpolycloid ribs in outer whorls; variable occurrence of simple ribs and intercalatories. Occurrence of complex ribbing on the inner whorls is a rarity, except for shells with high-crowded ribbing showing even subpolyplocoids, and some particular case with slightly lesser than normal crowding of ribs and the inclusion of polygyrates. Primary ribs number more variable at less than 50–60 mm, showing a persistent but variable increase at greater shell-size. When present, peripheral ribs number-secondaries plus intercalatories—commonly increasing throughout growth. Ventral ribs projected forwards, with variable occurrence of weakening of the mid-venter line, but without development of a true smooth band. Constrictions slightly oblique to ribs and better developed on planulate, loose-coiled shells. Dimorphic, with wide and very short lappets in accordance with the pre-apertural pattern of ribbing, gently concave-to-flexuous at the middle of the flank, and ventral rostrum (Fig. 7). The latter is assumed to be more or less projected in accordance with the lower or wider angle of the ventral chevron, respectively-colubrinoid to planulate microconchs versus planulate to discoid specimens, macroconchiates included. Macroconch: maximum adult size about 160 mm, evolute to very evolute (37–52%) with subrectangular whorl section. Constrictions common, narrow and shallow. Scarce subpolyplocoid ribs on the phragmocone and more frequent on the body-chamber. Rib curves per complete whorl and per half-a-whorl decrease in shells smaller than 40 mm. The body-chamber is about a whorl long; peristome simple” (taken literally from Villaseñor & Olóriz, 2019, p. 34).

Type locality: Rancho Los Alamitos, Sierra de Catorce, San Luis Potosí, Mexico.

Age: Lower not lowermost Tithonian (two-fold division) to the Lower-Middle Berriasian.

The whorl section after the colubrinoid stage is progressively higher during growth, with slightly convex to flattened and convergent flanks, and tabulate and wide venter with variable mid-venter depression. Scultpture made of mainly bifurcate, stif ribs with some simples and rarer intercalatories. The occurrence of a rare case of possible polygyrate rib is doubtful in the original types (forced by adjacent constriction in adoral position?). Ventral ribs projected forwards, with variable occurrence of weakening on the more or less depressed mid-venter line, but without development of true smooth band. Constrictions parallel to slightly oblique to ribs” (taken literally from Villaseñor & Olóriz, 2019, p. 35).

Holotype: T.G2.1.1

Original diagnosis: Dimorphic genus of small and medium size, with a wide, superficial or shallow umbilicus. The section is oval or subrectangular with flattened flanks and convex ventral region. The ornamentation is of unevenly strong and dense ribs, predominantly bifurcate, and some simple and polygyrated ones may be present at the end of the shell. In the macroconch there is a change in ornamentation consisting of finer and denser ribbing. All ribs pass through the ventral region without interruption. There may be soft constrictions parallel to the costulation. The suture line is simple, with few superficial lobulations, with the lateral saddle 1 and 2 unequally wide and divided into 2 by shallow invaginations, the lateral lobe trifid and the suspensory lobe with some or all of its oblique lobulations. The peristome is pedunculated in the microconchs and presumably simple in the macroconchs (translated from Tavera, 1985, p. 63).

Comments: Officially accepted genus in zoobank, https://zoobank.org/NomenclaturalActs/4a8d5ee7-8236-4f59-aee6-9bca12b119dc.

4.5 Mitta (2011)

  • Family Himalayitidae Spath, 1923

  • Genus Riasanella Mitta, 2011

  • Type species Riasanella rausingi Mitta, 2011

  • Riasanella olorizi Mitta, 2011 (fig. 1 a, b)

Holotype: PIN RAN, No. 3990/396

Original diagnosis: “Phragmocone of macroconchs reaches 70 mm in diameter, shell with a complete body chamber up to 80–85 mm. Phragmocone of microconchs reaches 45 mm, and the complete shell 55 mm in diameter. The whorls are flattened, with an oval cross-sect ion, narrowing towards the slightly flattened venter. The umbilicus is wide and (on the body chamber) very wide. The umbilical wall is narrow, with a rounded umbilical shoulder. The body chamber of macroconchs is up to 0.7 whorls; specimens with a preserved aperture are unknown. In Ihe only specimen of a microconch with a partly preserved lateral auricle (Dm ca. 55 mm) the beginning of the body chamber is missing, hence its total length is unknown. The ornamentation is represented by bifurcating, simple, and intercalating ribs. At Dm = 30–40 mm some ribs dichotomize in the umbilical region, and some near the mid-flank. The branches of the ribs are usually bent backward. Lateral bulges are frequently observed in the mid-flank. In microconchs, the ribs are crest-like and raised in the umbilical region. At the end of the phragmocone and on the body chamber, primary ribs are subradial, usually weakly bent, with distinct bulges in the umbilical regions and in the bifurcation point in the midflank. The branches are weakly crescent-like, bent orad. The ventrolateral shoulder possesses a nodelike inflation, smoothening in macroconchs toward the end of the body chamber” (taken literally from Mitta, 2011, p. 20).

Holotype: Univ. Granada, KS 412-25.

Original diagnosis: No provided by the author but description as follow. Elongated conical test, carrying a smooth horn of circular cross section and flattened cap-shaped end. The first three or four segments at the base of this horn bear uniformly dispersed nodules. For all the distal segments, except for the last two (which do not bear wrinkles), these nodules stretch into fine discontinuous and unaligned wrinkles. The outline of the test is marked by numerous tight constrictions (17 to 20); its external wall is finely perforated and shows, in addition to the discontinuous wrinkles, fine continuous longitudinal and transverse ribs whose meeting in two perpendicular directions determines square pore frames and gives the wall of the test a fine mesh appearance (translated from El Kadiri, 1992, p. 42).

Type locality: Oued El Halka, 5 km to SSW de Tétouan.

Age: Lower Jurassic (middle Toarcian to base of upper Toarcian).

5 Conclusion

The great academic trajectory of Federico Olóriz is market by his contributions to the systematic paleontology for ammonites. In his Ph.D. Thesis he proposed six new genera, two new subgenera, thirteen amended family, subfamily and genera, forty new species, and four new subspecies. Since the publication date almost all taxa style in use with minor inclusion in synonyms. Olóriz and coworkers (see Introduction chapter for references) proposed seven genera, one subgenus, 17 species and two subspecies. Federico Olóriz has studied ammonites coming from different geological setting in Spain and others part of the world (Table 1), but his outstanding contribution was in the Betic Cordilleras (Subbetic Zone) ammonites. The comments above reflects the deep and carefully work of the author. Indeed, the six taxa dedicated to him are examples of the recognition of Federico Olóriz great knowledge of the Jurassic ammonites and other fossils.
