Diagnosis

Reference	Diagnosis
Z. Dong et al. 1983	Skull is moderate in size with a well developed rostrum, quadrate is slightly anteriorly oblique, and supratemporal fenestra is large. Presacral series is long, with 17-19 opisthocoelous cervicals with relatively shallow pleurocoels, low neural spines, and bifid spines on the posterior cervicals. Cervical centra are 2 1/3 times the length of the dorsals. There are 12-14 opisthocoelous dorsals with generally well developed prezygapophyses. Three to four sacral vertebrae are present with the anterior three fused. Anterior caudals are procoelous, tibia is three-fifths the length of femur, and dentition is spoon-shaped.
