Summary

Description
English: A diagram of the skull of Azendohsaurus madagaskarensis, an allokotosaurian archosauromorph. Image is in right lateral view. Scale bar equals 1 centimeter. Modified from Flynn et al. (2010). Numbers indicate character states scored in the data matrix.

Character state scores=

  • 9-1: The external nares are confluent.
  • 16-1: The Orbit is subcircular in shape.
  • 21-2: The height of the snout at the tip of the maxilla is 0.59-0.80 times the height of the snout at the front edge of the orbit.
  • 27-1: The premaxillary body forms more than half of the snout in front of the rear edge of the external nares.
  • 36-2: The postnarial process of the premaxilla is well-developed, excluding the maxilla from participation in the external nares.
  • 64-1: The posterior end of the horizontal process of the maxilla is distinctly ventrally deflected from the main axis of the alveolar margin.
  • 99-1: The jugal possesses an ascending process which excludes the postorbital from the front edge of the infratemporal fenestra.
  • 111-1: The lateral surface of the orbital margin of the prefrontal possesses rugose sculpturing.
  • 131-1: The ventral process of the postorbital ends close to the ventral border of orbit.
  • 180-1: The dorsal end of the quadrate is hooked posteriorly in lateral view.
  • 267-2: The tooth-bearing portion of the dentary is ventrally deflected.
  • 283-1: The retroarticular process of the surangular and articular is short and poorly developed.
