Diagnosis
ReferenceDiagnosis
D. M. S. Watson 1958"C. hemprichi...very much resembles the Australian animal [Paracyclotosaurus davidi]. It differs in the shape of the tympanic membrane, which is "triangular" in contrast to circular. But in the structure of the occiput (apart from the presence of a well-marked shelf on the exoccipital for the supraoccipital cartilage) the two are very alike; the relation of the exoccipital to the pterygoid (Kuhn, 1942, pl. I, fig. Ib), the structures shown in his pl. I, fig. 3, and the structure of the quadrate-pterygoid region (pl. 3, fig. Ib) are extremely similar in the two animals."
