Bienosaurus (meaning "Bien's lizard") is a dubious genusofthyreophoran dinosaur from the Lower Jurassic (probably Sinemurian) Lower Lufeng FormationinYunnan Province in China.
In 1938, Bian Meinian, known in the West as Mei Nien Bien, discovered a fragmentary dinosaur skull. In 2001, Dong Zhiming named and described the specimen as the type species Bienosaurus lufengensis. The generic name honours Bian. The specific name refers to the Lufeng formation.[1]
Bienosaurus is based on holotype IVPP V15311 (in 2001 incorrectly given the inventory number IVPP V 9612). It consists of a partial right lower jaw with teeth and several cranial fragments.
Dong in 2001 placed Bienosaurus in the Scelidosauridae, considering these to be part of the Ankylosauria. Later publications suggested a general position basal in the Thyreophora. In 2019 a study confirmed this, concluding Bienosaurus was a nomen dubium, possibly identical to Tatisaurus from the same formation.[2]
