Chilantaisaurus tashuikouensis Hu, 1964

Age . Aptian-?Albian.

Occurrence. Unnamed unit, Nei Mongol Zizhiqu, China.

Diagnosis. Humerus with distally placed, subrectangular, pterosaur-like deltopectoral crest.

Remarks. Chilantaisaurus tashuikouensis is based on a partial postcranial skeleton, including elements of both the fore- and hindlimbs, from the Lower Cretaceous of China ( Hu 1964). In the original description, Hu (1964) described two species of Chilantaisaurus , based on non-comparable material. However, it seems very unlikely that both species belong to the same genus ( Chure 1998; see below). Since C. tashuikouensis is the first-described taxon in the original paper, it is designated as the type species of the genus here.

The species Allosaurus sibiricus Riabinin, 1914 has also been referred to the genus Chilantaisaurus ( Molnar et al. 1990) . However, this species is only based on an Allosaurus-hke metatarsal that is specifically and generically indeterminate, and should, therefore, be regarded as a nomen dubium.
