Mostrar todas las versiones(2)

Peirosaurids are a group of Cretaceous continental crocodyliforms from Gondwana. Two species are known from the Neuquén Group in Argentina: <i>Lomasuchus palpebrosus</i> (Portezuelo Formation, late Turonian–early Coniacian) and <i>Gasparinisuchus peirosauroides</i> (Bajo de l...

description Peirosaurids are a group of Cretaceous continental crocodyliforms from Gondwana. Two species are known from the Neuquén Group in Argentina: <i>Lomasuchus palpebrosus</i> (Portezuelo Formation, late Turonian–early Coniacian) and <i>Gasparinisuchus peirosauroides</i> (Bajo de la Carpa and Anacleto formations, Santonian and early Campanian, respectively). Here, we describe the first peirosaurid from the Cerro Lisandro Formation, <i>Bayomesasuchus hernandezi</i> gen. et sp. nov. The material corresponds to a fragmentary skull and mandible. Although fragmentary, this is the most complete crocodyliform specimen recorded for the Cerro Lisandro Formation. In a phylogenetic analysis <i>Bayomesasuchus</i> is depicted in a polytomy together with South American peirosaurids and the African form <i>Hamadasuchus rebouli</i>.
