Peirosaurids constitute a group of Gondwanan Cretaceous continental
crocodyliforms. Two species are known for the Neuquén Group,
Argentina: Lomasuchus palpebrosus Gasparini et al. (Portezuelo
Formation, Late Turonian–Early Coniacian) and Gasparinisuchus
peirosauroides Martinelli et al. (Bajo de la Carpa and Anacleto
formations, Santonian and Early Campanian, respectively). Here, we
describe the first peirosaurid from the Cerro Lisandro Formation,
Bayomesasuchus hernandezi 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 Bayomesasuchus is depicted in a
polytomy together with South American peirosaurids and the African
form Hamadasuchus rebouli
