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

Genera

Three genera are currently classified within Gobiosuchidae: Cassissuchus, Gobiosuchus, and Zaraasuchus.[1]

Synapomorphies

According to Pol & Norell (2004), 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
