Revize paleontologických nálezů z lokality Úsobrno

Le résumé fourni par la source

The Úsobrno locality is known on the basis of fossil fauna findings, which were documented and published by Vašíček (1941). Field research has not been able to find the original locality yet. In this reason paleontological material which is deposited in the collections of ÚGV PřF MU was researched. We identified a total of 573 species which belonged mainly to the classes Gastropoda, Bivalvia, Anthozoa and Scaphopoda and compared with the original findings mentioned by Vašíček (1941). The age of the samples was determined to be the Lower Badenian.Based on the findings, especially hermatypal corals, it can be assumed that the sea was warm (above 20 °C), well oxygenated with a soft and hard bottom and mostly shallow. Some findings of fauna from deeper marine areas (Ranella fragment, ahermatypal corals) indicate mixing or postmortem transport during sedimentation.
