Diagnosis
ReferenceDiagnosis
E. C. Olson and H. Barghusen 1962A species of Cotylorhynchus of approximately the same over-all size as C. romeri Stovall, but differing in proportions, particularly proportion of limb bones (table 3). Pelvis with high iliac blade. Radius and ulna relatively slender and short. Femur with slender shaft. Astragalus with very large foramen. Maxillary teeth with distinct, longitudinal, tricuspid pattern, similar to that of C. hancocki Olson and Beerbower, but more highly developed than in comparable teeth of that species.
