Jiangjunosaurus

• China ( Xinjiang )

• J. junggarensis Jia et al. 2,007

Jiangjunosaurus is a sparsely -known dinosaur species from the group of Stegosauria, which was described in 2007.

From Jiangjunosaurus only the lower jaw, isolated parts of the skull, cervical vertebrae, as well as several individual bone plates are previously known. Characteristic of the genus were the symmetric and relatively wide tooth crowns, otherwise little is known about this dinosaur. He was probably like all Stegosauria characterized by a double row of bony plates on its back, moving away quadruped and fed on plants.

The fossil remains of Jiangjunosaurus were in the Shishugou Formation in the Junggar Basin discovered in the Chinese province of Xinjiang and 2007 by Jia Chengkai et al. first described. Only known type and therefore the type species is J. junggarensis. The finds are in the Upper Jurassic ( Oxfordian ) dated to an age of about 163-157 million years.

In the estimation of describer is in Jiangjunosaurus a relatively basal representatives of Stegosauria. He is a bit more sophisticated than Huayangosaurus, but have been primitive than most other members of this group. Because of sparse finds such results are not regarded as provisional.
