"Crocodylus" gariepensis is an extinct species of crocodile that lived in southern Africa during the Early Miocene about 17.5 million years ago (Ma). Fossils have been found along a bank of the Orange River in Namibia, near its border with South Africa. Although much of Namibia is currently arid, "C." gariepensis lived during a time when the local climate was humid and subtropical. It likely inhabited gallery forests surrounding the Orange River. Fossils of giant tortoises and a variety of small burrowing mammals have been found in the same deposits.
