The Caseosaurus may be the same dinosaur as Chindesaurus. Both dinosaurs are from the same geological area as well as being dated in the late Triassic Period. The Caseosaurus was found in the Dockum Formation of Texas. It was named after E.C Case, an artistic paleontologist.

The carnivore was described by Hunt, Lucas, Heckert, Sullivan and Lockley in 1998. The Caseosaurus was discovered as just a partial skeleton therefore is was so imcomplete that it could not be set in a classification or taxon.
