Yueosaurus is an extinct genus of basal neornithischian dinosaur known from Zhejiang Province, China. [1]

Description

Yueosaurus is known only from the holotype ZMNH  M8620, an articulated, partial but well preserved postcranial skeleton which includes cervical, dorsal (back) and caudal vertebrae, scapula, rib, hip bones, partial forelimb and partial hindlimb. It was collected in Tiantai locality from the Liangtoutang Formation, dating to the Albian-Cenomanian stages of the latest Early Cretaceous and the earliest Late Cretaceous. Yueosaurus represents the southernmost basal ornithopod dinosaur from Asia, and the first one from China. It differs from other ornithischians by a combination of characters. [1] Han et al. found it plausible that Yueosaurus might be a member of Jeholosauridae or closely related to it. [2]

Etymology

Yueosaurus was first named by Wenjie Zheng, Xingsheng Jin, Masateru Shibata, Yoichi Azuma and Fangming Yu in 2012 and the type species is Yueosaurus tiantaiensis. The generic name is derived from "Yue", the ancient name for Zhejiang, and the specific name refers to the Tiantai, where the holotype was discovered. [1]

<i>Cedarpelta</i> Extinct genus of reptiles

Cedarpelta is an extinct genus of basal ankylosaurid dinosaur from Utah that lived during the Late Cretaceous period in what is now the Mussentuchit Member of the Cedar Mountain Formation. The type and only species, Cedarpelta bilbeyhallorum, is known from multiple specimens including partial skulls and postcranial material. It was named in 2001 by Kenneth Carpenter, James Kirkland, Don Burge, and John Bird. Cedarpelta has an estimated length of 7 metres and weight of 5 tonnes (11,023 lbs). The skull of Cedarpelta lacks extensive cranial ornamentation and is one of the only known ankylosaurs with individual skull bones that are not completely fused together.

Zhejiangosaurus is an extinct genus of ankylosaurian dinosaur from the Upper Cretaceous of Zhejiang, eastern China. It was first named by a group of Chinese authors Lü Junchang, Jin Xingsheng, Sheng Yiming and Li Yihong in 2007 and the type species is Zhejiangosaurus lishuiensis. It has no diagnostic features, and thus is a nomen dubium.

The only species is Dongyangosaurus sinensis, from which only a single fragmentary skeleton is known, coming from the Zhejiang province of eastern China. It was described and named by Lü Junchang and colleagues. Like other sauropods, Dongyangosaurus would have been a large quadrupedal herbivore.

Ahshislepelta is a monospecific genus of ankylosaur dinosaur from New Mexico that lived during the Late Cretaceous in what is now the Hunter Wash Member of the Kirtland Formation. The type and only species, Ahshislepelta minor, is known only from an incomplete postcranial skeleton of a small subadult or adult individual. It was named in 2011 by Michael Burns and Robert M. Sullivan. Based on the size of the humerus, Ahshislepelta is larger than Pinacosaurus mephistocephalus but smaller than Talarurus and Pinacosaurus grangeri.

The Khok Kruat Formation is a rock formation found in northeastern Thailand. It is the uppermost formation of the Khorat Group.

The group is a fluvial formation consisting primarily of red siltstones and sandstones.

Dongyangopelta is an monospecific genus of nodosaurid dinosaur that lived in China during the Early to Late Cretaceous period in what is now the Chaochuan Formation.

It was named in 2013 by Rongjun Chen, Wenjie Zheng, Yoichi Azuma, Masateru Shibata, Tianling Lou, Qiang Jin and Xinsheng Jin. Dongyangopelta represents one of the only nodosaurids known from Asia, along with Taohelong and Sauroplites.
