Diagnosis
ReferenceDiagnosis
D. Pol and M. A. Norell 2004Small crocodyliform diagnosed by the following combination of characters: sculptured skull bones that are ornamented with thin and continuous ridges; anterior margin of infratemporal fenestra almost completely formed by the postorbital; retroarticular process with a pointed, well developed posterolateral process, the surface of which is ornamented; extremely well-developed keels on dorsal and lateral cervical osteoderms, the heights of which are approximately equal in length to the lateromedial extension of the dorsal osteoderms.
