Abstract
The way in which the ostracod carapace decomposes through biological and physico-chemical processes is illustrated with Recent and Neogene non-marine ostracods (candonines, herpetocyprines and cytherids) from lacustrine and groundwater habitats. The degree of carapace preservation for Recent Candoninae, in the Mondsee (Austria) is shown to be dependent on the sedimentary microenvironment. The carapaces of herpetocyprines, because of their special morphological structure, decay very easily. This could explain the rare occurrrence of this ostracod group in Palaeogene deposits in Europe.
