Sažetak

Many new ostracod species from the Northern Adriatic Sea are based on descriptions of empty valves that were nevertheless interpreted as being parts of recent marine habitats and listed in several zoological checklists and databases. Sedimentary-geological studies contradict this interpretation. Ostracods from 2 cores taken off the Istrian Coast prove the existence of a relatively uniform subsurface layer with a rich death assemblage from a palaeoenvironmental depth zone prior or equal to the sea-level that existed 7–5 ka BP, related to the postglacial sea-level change. This layer was covered by patches with extremely different ostracod bio-, thanato- or palaeothanatocoenoses, depending on storm re-deposition, lag deposition or bioturbation. In terms of sequence stratigraphy, the Maximum Flooding Surface and a condensed Highstand Systems Tract are still forming the bottom areas more than 5 km off the Istrian Coast.
