Mo J., Xu X. & E. Buffetaut, 2010.  A new eusauropod dinosaur from the Lower 
Cretaceous of Guangxi Province, Southern China.  Acta Geologica Sinica 84 (6): 
1328-1335.
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.
