''Bayomesasuchus'' is an extinct genus of peirosaurid mesoeucrocodylian known from the early Late Cretaceous Cerro Lisandro Formation of Neuquén Province, western central Argentina. It contains a single species, ''Bayomesasuchus hernandezi''. Even though it is known from relatively fragmentary remains, it represents one of the most basal peirosaurids. ==Discovery== ''Bayomesasuchus'' was fist described and named by Francisco Barrios, Ariana Paulina-Carabajal and Paula Bona in 2015 and the type species is ''Bayomesasuchus hernandezi''. The generic name refers to the Cerro Bayo Mesa mountain, located in southeastern Neuquén Province of Argentina, where the holotype was found, and ''suchus'', Latinized from the Greek ''souchos'', an Egyptian crocodile god. ''Bayomesasuchus'' is known solely from its holotype, a fragmentary skull and mandible. It was collected form the Cerro Lisandro Formation which is the youngest formation within the Río Limay Subgroup, the lowest section of the Neuquén Group, dating to late Cenomanian to early Turonian of the early Late Cretaceous.〔 The holotype of ''Bayomesasuchus'' is the most complete crocodyliform specimen recorded from the Cerro Lisandro Formation, and represents the forth peirosaurid named from the Neuquén Group of Argentina, together with ''Lomasuchus palpebrosus'' and ''Patagosuchus anielensis'' from the overlying late Turonian to early Coniacian Portezuelo Formation, and ''Gasparinisuchus peirosauroides'' from the even younger Santonian to early Campanian Bajo de la Carpa and Anacleto Formations.〔
