Bienosaurus lufengensis
(Bien's Lizard from Lufeng)Etymology
Bienosaurus is derived from "bien" (for Chinese palaeontologist Mei Nien Bien) and the Greek "sauros" (lizard).
The
species epithet,
lufengensis, means "from Lufeng" in Latin.
Discovery
The remains of
Bienosaurus were discovered in the Dark Red Beds of the Lower Lufeng Formation, Yunnan Province, China, by Mei Nien Bien between 1938 and 1939. The holotype (IVPP V15311) is a partial lower jaw and some skull fragments.
Originally, this specimen was catalogued as IVPP V 9612. But that had already been attached to the holotype of
Sinornithoides youngi, a troodontid theropod dinosaur from the Early Cretaceous Ejinhoro
Formation of Inner Mongolia.
