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 == Sources ==
