If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
|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."|
