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

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
