Fauna wealdiană din bauxitele de la Cornet - lentila 204, judeţul Bihor în comparaţie cu faune de vârstă similară din Anglia

  • Subiect: The Wealden fauna, exceptionally conserved in bauxites from Cornet - Lentila 204, Bihor County, consists of scheletal remains of dinosaurs, pterosaurs and birds. The predominance of omithopods is remarkable, two taxa have been identified: Camptosaurus and Valdmaurus; as well as an ankylosaur and a small-sized theropod, but these are extremely rare. The Wealden fauna of South-East England is dominated by omithopod dinosaurs, but sauropods and theropods are relative abundent as well. Fish, crocodile and turtle remains were also identified, which are totally absent in the Comet assemblage. In the English deposits there is a rare occurence of pterosaurs and mammals. The most remarkable difference is the size of the vertebrates, those from Cornet being of more reduced sized in comparison with those from England, which is an evidence for early geographical isolation and evolution in insularity, attested by the low diversity of the dinosaurs.
