Tecovasaurus (te-KOH-va-SAWR-us) is an extinctLate Triassicamniotegenus of unknown affinities, known only from teeth. It was initially described as a basal ornithischiandinosaur, subsequently reclassified as a member of the clade Archosauriformes of uncertain phylogenetic placement (Irmis et al. (2007), and later, taking into account the similarity of its teeth to the teeth of traversodontidcynodonts such as Dadadon (shared presence of teeth with sub-triangular crowns, enlarged denticles, and thecodont tooth implantation), as an amniote of uncertain affinities (Kammerer et al., 2012; though "based on dissimilarities in gross morphology and geographic separation" the authors considered it more likely that the taxon is indeed an archosauriform rather than a traversodontid). It is named after the Tecovas Formation, in Texas and Arizona, which yielded the holotype remains.
