An Adult Specimen of Hongshanosaurus houi （Dinosauria： Psittacosauridae） from the Lower Cretaceous of Western Liaoning Province, China
摘要
A new specimen consisting of a complete skull and lower jaw was discovered from the Lujiatun bed of the Lower Cretaceous Yixian Formation in the Lujiatun site, Beipiao, western Liaoning Province. It represents an adult specimen of Hongshanosaurus houi. Comparative studies show that Hongshanosaurus is distinguishable from its sister taxon Psittacosaurus by having the preorbital portion about half of the basal skull length, and the elliptical external naris,orbit, and a lower temporal fenestra oriented caudodorsally.
