There is only a partial [[skull]] from [[strata]] in western [[Texas]]. Skull features, like the housing of the [[cochlea]], suggest that ''Adelobasileus'' is a [[Transitional fossil|transitional form]] in the evolution from [[cynodont]]s to end-Triassic mammals. For this reason, it may be close to modern mammals' [[Common descent|common ancestor]].<ref>Lucas S.G. & Hunt A.P. 1990. The oldest mammal.
