[D] Jiangjunosaurus junggarensis [Su] [sG] [T]
Describer
Jia, Forster, & Clark 2007
Time
Jurassic Late Oxfordian
Classification
Ornithischia Thyreophora Stegosauria Stegosauridae
Diet
Herbivore
Fossilsite
Shishugou Formation, Jiangjunmiao, Junggar Basin, Xinjiang, China
Info
Genus - Typespecies - Skull
Etymology
\\\\\\\"Jiangjun\\\\\\\", Chinese \\\\\\\"general\\\\\\\", and \\\\\\\"saurus\\\\\\\", Greek, \\\\\\\"lizard; the generic name is derived from the deserted town of Jiangjunmiao near the holotype locality, named for an ancient general who died nearby. The specific name is derived from the Junggar Basin, the large geographical area that includes the type locality.
Holotype
IVPP V 14724, a partial articulated skeleton, including partial skull, an allmost complete mandible, 11 artticulated cervical vertebrae, some ribs and two dermal plates. The cranial sutures are tight but not closed or fused. Fusion is also incomplete between the odontoid process and axial centrum, between the atlantal neural arches and centrum, and the scapula and coracoid. Yet, the interptergoid vacuity is not present on the palate and neuralcentral sutures of all other cervical vertebrae are closed. These features suggest that the holotype is a sub-adult individual.
Diagnosis
A stegosaur different from other species in the following features: tooth crowns symmetrical and proportionally wide mesiodistally; a sub-retangular axial neural spine; and large openings on the lateral surface of the posterior cervical centra.
