Gobiosuchidae

Gobiosuchidae is a family of Cretaceous crocodyliforms known from Mongolia and Spain.

Genera

Three genera are currently classified within Gobiosuchidae: Cassissuchus, Gobiosuchus, and Zaraasuchus.

According to Pol & Norell, gobiosuchids form a clade united by the following synapomorphies:

Parietal without broad occipital portion
Absence of external mandibular fenestra
More than two parallel rows of dorsal osteoderms
Cranial table as wide as ventral portion of skull
Palpebrals sutured to each other and the frontal, excluding it from the orbital margin
External surface of ascending process of jugal exposed posterolaterally
Longitudinal ridge on lateral surface of jugal below infratemporal fenestra
Dorsal surface of posterolateral process of squamosal ornamented with three longitudinal ridges
Presence of a sharp ridge along ventral surface of angular
Surangular with a longitudinal ridge on its dorsolateral surface
Dorsal surface of osteoderms ornamented with anterolaterally and anteromedially directed ridges
Cervical region surrounded by lateral and ventral osteoderms sutured to the dorsal elements
Presence of appendicular osteoderms
Closed, or incipiently close, supratemporal fenestra
