Lu, J., Azuma, Y., Chen, R., Zheng, W., and Jin, X. (2008) A new titanosauriform sauropod from the Early Late Cretaceous of Dongyang, Zhenjiang Province: Acta Geologica Sinica, v. 82, n. 2, p. 225-235.

Abstract: A new titanosauriform sauropod Dongyangosaurus sinensis gen. et sp. nov. from the early Late Cretaceous of Dongyang County, Zhejiang Province, is erected based on a partial postcranial skeleton. It is characterized  by complex laminae on the lateral surface of the neural spines and postzygapophyses of dorsal vertevrae, a distinct fossa on the ventral surfaces of the prezygapophyses of dorsal vertebrae, distinct fossae are also present on the lateral surface of the postzygapophyses of anterior caudal vertebrae; pubis is shorter than ischium, the small obturator foramen of pubis elongated, and nearly closed. The lamina complexity of dorsal vertebrae in Dongyangosaurus indicates that a higher diversity of titanosauriforms occurred during the early Late Cretaceous.
