Tecovasuchus
''Tecovasuchus'' is an extinct genus of aetosaur. It is known primarily from osteoderms found from the Tecovas Formation in Texas, which is Late Triassic in age, dating back to the upper Carnian. Material is also known from several other localities of the Chinle Group in New Mexico and Arizona. Specimens of ''Tecovasuchus'' have been collected from the Tecovas Formation, the Bluewater Creek Formation, and the Los Esteros Member of the Santa Rosa Formation.
''Tecovasuchus'' was first recognized as a new taxon in 1995, although it was not named until the description of the type species, ''T. chatterjeei'', in 2006. Before its description, specimens of ''Tecovasuchus'' were thought to belong to ''Paratypothorax'' or a ''Paratypothorax''-like aetosaur.〔 Several features of the osteoderms distinguish ''Tecovasuchus'' from other aetosaur genera, including dorsal paramedian osteoderms with strongly thickened and beveled posterior edges and ornamentation consisting of deep pits and radiating grooves, as well as tongue-shaped dorsal and plate-like ventrolateral flanges.
''Tecovasuchus'' is an index taxon for the St. Johnsian sub-LVF (land vertebrate faunachron) of the Adamanian LVF, and the presence of material belonging to the genus helps correlate different Late Triassic localities throughout the southwestern United States.〔
