New Crocodylomorpha specimens are described for the Jurassic in Brazil.
New contributions to the knowledge about the Jatobà Basin biota including Goniopholididae.
First described Crocodylomorpha from the Jatobà Basin, Brazil.
Abstract
Up to date, at least 50 species of Crocodylomorpha are known in Brazil. Those species are distributed in a temporal range from the Triassic to the present day. However, Crocodylomorpha records from the Brazilian Jurassic are quite scarce, and they have been often considered as lacking enough information for a proper systematic identification. In this study, we describe new Crocodylomorpha specimens, collected in Ibimirim city, Pernambuco state, Northeast of Brazil, where outcrops of the AlianÃa Formation (Upper Jurassic), Jatobà Basin, have been recorded. The specimens are represented by teeth, frontal plate, vertebrae, and osteoderms. Despite fragmented, these Crocodylomorpha remains allowed us, based mainly on morphological evidence in the teeth, to visualize intermediate characteristics between the Goniopholididae and Teleosauridae. The present work reveals the high, and still little explored, paleontological potential of the AlianÃa Formation in the understanding of the Brazilian Jurassic.
