Trilophosuchus
''Trilophosuchus'' ("Triple Crest Crocodile") is an extinct genus of mekosuchine crocodilian from Australia. Unlike living crocodilians, it is hypothesized to have been terrestrial. ''Trilophosuchus'' was approximately in length. It had a short skull with three ridges on top and large eyes. Fossils have been found at Riversleigh in north-western Queensland, and are Miocene in age. Only a single species has been described, the type species ''T. rackhami''.
==Discovery==
''Trilophosuchus'' is known from a posterior portion of the skull, QM F16856, the holotype specimen. Several other isolated bones of the skull were found. The material was collected from the Ringtail Site of the Gag Plateau in Riversleigh, one of Australia's most famous fossil localities. The skull was uncovered in 1985 during an excavation by the University of New South Wales. The deposit in which ''Trilophosuchus'' were found are Early Miocene in age, roughly 20 million years old. The deposit, known as System C, is the youngest of the Oligocene-Miocene sequences at Riversleigh. The genus ''Trilophosuchus'' was erected in 1993 with the description of the remains by Paul Willis of the University of Sydney in the ''Journal of Vertebrate Paleontology''.
