Cretaceous of Guangxi Province, Southern China. Acta Geologica Sinica 84 (6):
Abstract: A new sauropod dinosaur, *Liubangosaurus hei* gen. et sp. nov., is
erected based on a specimen represented by five articulated middle-caudal
dorsal vertebrae, which was discovered in the Lower Cretaceous Napai Formation
of Guangxi Province, southern China. This new taxon is diagnosed by a unique
combination of derived features: prezygapophysis closely contacts with
parapophysis, with the prdl and prpl absent; presence of cavity on the dorsal
surface of the diapophysis; neural spine very low, with its distal end level
with that of diapophysis; distal end of the neural spine strongly expanded
laterally to form a platform; marked fossa formed between the
infradiapophyseal lamina and the parapophysis; broad, flat area of featureless
bone on lateral surface of neural arch; vertically directed infradiapophyseal
lamina expands or bifurcates ventrally to form a inverted “Y”; highly
positioned parapophyses large and tear-drop in shape. The discovery of this new
taxon increases the diversity of sauropods in China during the Early Cretaceous.
Lü J., Y. Kobayashi, Li T. & Zhong S., 2010. A new basal sauropod dinosaur
from the Lufeng Basin, Yunnan Province, southwestern China. Acta Geologica
Sinica 84 (6): 1336-1342.
Abstract: A new dinosaur *Chuxiongosaurus lufengensis* gen. et sp. nov. is
erected based on a nearly complete skull. The taxon is characterized by the
lacrimal perpendicular to the ventral margin of the upper jaw, which is similar
to that of *Thecodontosaurus*; a depression present on the dorsal profile of
the snout behind the naris; the rostral profile of the maxilla slopes
continuously towards the rostral tip; and the presence of 25 dentary teeth. It
also displays prosauropod characters such as a relatively long skull, the slope
of the maxillary rostral profile, and teeth that do not have basically
constricted crowns. The new specimen is more basal than *Anchisaurus* and
represents the first basal sauropod dinosaur from the Early Jurassic of China.
