Reason: There is no differentiation between the premaxilla and maxilla, the nasals apparently diverge from each other at their front ends, there's no differentiation between the nasals and lacrimals, the lacrimals form part of the jaw line, there seems to be a maxillary ascending process, the lacrimal appears boomerang-shaped rather than triradiate, the maxilla is involved in the external narial border, there appears to be no quadrate and therefore no jaw joint, there's no differentiation between the dentary and surangular, the angular/splenial extends to the front of the mandible and forms the tip of the jaw while being exposed laterally throughout the entire length, the upper end of the humerus is significantly wider than the lower, there is an anterior accessory epipodial which contacts the humerus with a well-developed preaxial accessory digit distal to it, the posterior margin of the ulna is notched, digit II is not bifurcated, the phalanges do not interlock, and the ischium does not contact the ilium.
