Lorosuchus is an extinct genus of sebecid mesoeucrocodylian known from the Río Loro Formation in Tucumán Province of northwestern 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 Río Loro Formation, dating to the Thanetian or the Selandian stage of the Middle to Late Paleocene, about 61.7 to 55.8 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.
