Abstract: Trilophosaurus is an aberrant archosauromorph from the Upper Triassic Chinle Group of the southwestern United States. We review the history of study of Trilophosaurus, revise the diagnosis of the genus and both species of Trilophosaurus, T. buettneri Case and T. jacobsi Murry, and summarize its biostratigraphic record. Reevaluation of T. dornorum Mueller and Parker reveals no diagnostic differences between it and T. jacobsi, rendering T. dornorum a junior subjective synonym of T. jacobsi. The two species of Trilophosaurus have well established temporal ranges, with T. buettneri extending from the middle Otischalkian to late Adamanian and T. jacobsi extending from early Adamanian into the Revueltian.
