New sauropod in Geological Bulletin of China: Ruyangosaurus giganteus

I don't believe this one has been mentioned yet:

Lu J., Xu L., Jia S., Zhang X., Zhang J., Yang L., You H., Ji Q. 2009. A new gigantic sauropod dinosaur from the Cretaceous of Ruyang, Henan, China. Geological Bulletin of China 28(1).

Abstract: The new gigantic sauropod dinosaur Ruyangosaurus giganteus gen. et sp. nov. from the early Late Cretaceous Mangchuan Formation of Ruyang, Henan, China is described. It is characterized by a lower neural spine, lack of centroprezygoapophyseal lamina, a large, irregularly triangular deep fossa on the lateral surface of the neural arch, the prezygodiapophyseal lamina oriented anteroposteriorly, and a robust tibia, some 127 cm in length. The discovery of Ruyangosaurus indicates that a higher diversity of sauropod dinosaurs occurred during the early Late Cretaceous than previously thought.

Thanks to George O. for the tip, and to DinoData for posting the abstract and reference. (Haven't seen the actual paper yet.)
