Diagnosis
ReferenceDiagnosis
X. Wang et al. 2015Rostrum approximately 60% of the skull length; dentition restricted to premaxilla and the rostral-most portion of dentary; large, recurved and labiolingually compressed teeth with crenulations developed along the caudal margins; middle cervical vertebrate heterocoelous; distal region of sternum with developed carina and lateral processes; coracoids with nearly straight lateral margin; second phalanx of minor digit reduced to a small triangle; pubis curved and with perpendicular pubic-foot; tarsometatarsus fused proximally, metatarsal IV surpasses the distal end of metatarsal III; ratio of tibiotarsus length to tarsometatarsus length approximate 1.6; trochleae of metatarsals I-IV almost on the same level; tibiotarsus shorter than humerus and ulna (modified from Zhang et al. 2001 & O’Connor et al. 2011).
