I ran across this while browsing on the internet. I do not believe it has been
mentioned on list, so I thought I would introduce Ruyangosaurus giganteus.
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).
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.
