Diagnosis
ReferenceDiagnosis
C. A. Marsicano et al. 2024Distinguishable from all other tetrapods by the unique presence of a wide and flat subtrapezoidal cultriform process of the parasphenoid; interpterygoid vacuities small, elongated and strongly tapered anteriorly; there is a large and a small fang pair on each vomer (the large pair being lateral to the small pair) and each pair comprises one standing fang and a replacement pit; vomerine fangs interlock
with similar fangs on the anterior coronoid and those in the symphysis; presence of subdued ornamentation around each skull table bone; skull ornamentation dominated by a ridge-and-furrow pattern; labial surface of the anterior coronoid distinctively bulging with deep fossa accommodating enlarged fang pair.
