A new sauropod dinosaur Baotianmansaurus henanensis gen.et sp.nov.from the Cretaceous Gaogou Formation of Neixiang,Henan Province is erected.It is characterized by somphospondylous presacral vertebrae;a highly-developed lamina system on the dorsal vertebrae;transverse process supported by four laminae;and the dorsal portion of the anterior centroparapophyseal lamina is bifurcated,with a small branch extending to the ventral surface of the prezygapophysis.It represents a new titanosauriform sauropod.
