Coahomasuchus is an extinct genus of aetosaurine stagonolepidid. Fossils have been found from the Dockum Group in western Texas and date back to the Otischalkian faunachron (lower late Carnian) of the Late Triassic[1]. It was small for an aetosaur, being less than 1 meter long. The dorsal plates are distinctively flat and unflexed, and have a faint sub-parallel to radial ornamentation. The genus lacked spines or keels on these plates, features seen in many other aetosaurs[2]. Coahomasuchus was very similar in appearance to the closely related Aetosaurus.
