Bienosaurus (meaning "Bien's lizard") was a dinosaur from the Early Jurassic. The genus was an armoured dinosaur from the Lower Lufeng Formation in Yunnan Province in China.

Discovery and species[edit]

In 1938, Bian Meinian discovered a fragmentary dinosaur skull. In 2001, Dong Zhiming named and described the specimen, based on a right lower jaw and teeth. Other known material includes a nearly complete right mandibular ramus with teeth and several cranial fragments. The type species is B. lufengensis. It is believed to share close affinities with Scelidosaurus.
