Rich fauna in the Upper Cretaceous of Romania

An outcrop in southern Transylvania displays Upper Cretaceous transitional sediments from a marine to brackish environment with terrestrial elements. An international research group (including three members of the Institute of Paleobiology) conducted a comprehensive faunal study of this outcrop and identified 102 taxa of organisms, including nannoplankton, plant seeds and fruits, corals, bivalves, snails, ammonites, sea urchins, starfish, sharks, ray-finned fish, anurans, squamates, crocodiles, and putative dinosaur eggshells.
