Lorosuchus
''Lorosuchus'' is an extinct genus of sebecid mesoeucrocodylian known from Tucumán Province of north-western Argentina. ==Discovery== ''Lorosuchus'' is known from the holotype PVL 6219, a nearly complete skull found articulated with the lower jaws and fragmentary postcranial remains. It was collected at the southern end of Medina Range, near the El Cadillal Lake from the Rio Loro Formation, dating to the Thanetian or the Selandian stage of the middle-late Palaeocene, about 55.8-61.7 million years ago. ''Lorosuchus'' is characterized by a unique combination of characters, including five autapomorphies such as an elevated narial rim and the presence of a crest on the anteromedial margins of both premaxillae. Phylogenetically, ''Lorosuchus'' is currently recognized as the basalmost known sebecid.〔
