Diagnosis
ReferenceDiagnosis
D. Pol and M. A. Norell 2004Small and extremely short snouted crocodyliform with an extensive anterodorsal lacrimal process wedging between the nasal and maxilla, contacting anteriorly the posterodorsal process of premaxilla. Palatines forming a posteriorly extended secondary palate, almost reaching the posterior edge of the pterygoid flanges where the secondary choana is located. Posttemporal region of the parietal extremely narrow, wedging between the squamosals (paralleled in Gobiosuchus). Reduced upper dentition, premaxilla with three teeth and maxilla with five teeth (paralleled in some mesoeucrocodylians).
