The largest " C . thorbjarnarsoni " skull found ( KNM-ER 1682 ) measures from the tip of the snout to the back of the skull table, in comparison, the largest known extant " Crocodylus " skull is that of a saltwater crocodile, measuring.

These skeletons provided much of the information used to distinguish " O . kitchingorum " from the type species . " O . kitchingorum " differed from " O . rubidgei " in that it possessed small postparietals on the posterior edge of the skull table and that the maxilla held no more than 20 teeth, some of which were caniniform.

Features that distinguish " A . hooleyi " from " Goniopholis crassidens " include the lack of a hole in the lower jaw called the mandibular fenestra, very wide supratemporal fenestrae ( openings ) on the skull table, and a bone above the eye socket called the palpebral that is small and does not extend over the socket as in some other goniopholidids.

Among crurotarsans, vertebrae that are each overlain by a single row of pitted, paired osteoderms as in " Tarjadia " are seen in aetosaurs, phytosaurs, and Crocodylomorpha . " Tarjadia " has been distinguished from aetosaurs by its apparent lack of an anterior articular lamina ( a depressed region along the front of each osteoderm ), and clear differences in the skull tables . " Tarjadia " differs from sphenosuchians and proterosuchians, the two main Triassic crocodylomorph groups, in that its osteoderms lack any clear structures on the anterior edges of the osteoderms.
