Diagnosis
ReferenceDiagnosis
K. Li et al. 2010Pleurocoels are developed in all presacral vertebrae, and the bone texture is solid. Pleurocoels are large and deep. Cervical centra are slender. A ventral keel is present on
each cervical centrum. Posterior cervical centra have well developed laminae and cavities. Both laminae and pleurocoels are well developed in the dorsal vertebrae. Cervical and anterior dorsal centra are opisthocoelous, middle dorsal centra are platycoelous, posterior dorsal and anterior caudal centra are amphicoelous. Centra lack a cancellous structure. Forelimb length is 0.80 of hindlimb length. Humerus is straight and robust, and deltopectoral crest is well developed. Femur is straight and robust with a well developed 4th trochanter.
