The Tecovas Formation is a geological formation in the Texas panhandle and eastern New Mexico. It is one of several formations encompassed by the Late Triassic Dockum Group.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Triassic, North America)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 518–521. .
The lower unit of the Cooper Canyon Formation in Garza County to the south is stratigraphically equivalent to the Tecovas Formation. It is also contiguous with the Garita Creek Formation of New Mexico, as well as partially to the Santa Rosa Formation.
