| The Lower Permian vertebrate bearing sites in Tillman County, Oklahoma, the N.E. Frederick and W. Grandfield Sites, were studied to expand the knowledge of vertebrate paleontology of the Garber Formation as well as determine the paleocology at these two sites.; At the N.E. Frederick Site the fossiliferous zones are in a large lense of predominantly gray claystone which contains a large fauna and flora. Included at the site are remains of many vascular plants, pelecypods, tubular worms, fish (Xenacanthus, Orthacanthus, Anodontacanthus, Hybodus, Sagenodus , paleoniscoids), amphibians (Eryops, Trimerorhachis, Diplocaulus, Diadectes, Archeria) and reptiles (Captorhinus, Ophiacodon, Edaphosaurus, Dimetrodon).
