Lorosuchus

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.
Etymology.
"Lorosuchus" was named by Diego Pol and Jaime E. Powell in 2011 and the type species is "Lorosuchus nodosus". The generic name is derived from "Loro" in reference to the Río Loro Formation in which "Lorosuchus" was found, and "suchus", Latinized from the Greek "souchos", an Egyptian crocodile god. The specific name named after the particular ornamentation of the dorsal surface of the skull, which resembles the non-related, basal archosauriform "Proterochampsa".
