Small horned dinosaur from China, a Triceratops relative, walked on two feet

Many dinosaur species are known from scant remains, with some estimates suggesting 75% are known from five or fewer individuals. Auroraceratops rugosus was typical in this regard when it was named in 2005 based upon a single skull from the Gobi Desert in northwestern China. But that is no longer the case.
