        Abstract:

Ceratopsid dinosaurs represent one of the best known dinosaur groups in the
Late Cretaceous, and their unquestionable fossil rec-ords are exclusively
restricted to western North America. Here we report a new ceratopsid
dinosaur, Sinoceratops zhuchengensis gen. et sp. nov., from the Upper
Cretaceous Wangshi Group of Zhucheng, Shandong Province, China. Cladistic
analysis places this new taxon as the only known ceratopsid from outside
North America, in a basal position within the Centrosaurinae. It is
con-siderably larger than most other centrosaurines but similar in size to
basal chasmosaurines. Furthermore, it is more similar to chasmosaurines than
to other centrosaurines in several features, thus blurring the distinction
of the two ceratopsid subgroups. This new find not only provides significant
information on the morphological transition from non-ceratopsid to
ceratopsid dinosaurs, but also complicates the biogeography of the
Ceratopsidae, and further demonstrates that fossil sampling has profound
effects on recon-structing dinosaurian biogeography.
