[D] Jiangshanosaurus lixianensis [sG] [T]
Describer
Tang, Kang, Jin, Wei & Wu 2001
Time
Cretaceous Early Albian
Classification
Saurischia Sauropodomorpha Sauropoda Titanosauria
Diet
Herbivore
Fossilsite
Jinhua Formation, Jiangshan, Zhejiang Province, China
Info
Genus - Typespecies
Collected by Wei Feng, Wu Wei-Tang and Kang Xi-Min from the lower part of Jinhua formation in Albian (105Ma) horizon. J. lixianensis is the first Titanosaurid known from China. The preserved part is fairly complete. Compared to the sauropod skeletons in China and other nations from Late Jurassic and Cretaceous, the diagnosis of scapulocorcoid and vertebrae of the new genus is most similar to those of Titanosauria, especially Alamosaurus.
Etymology
Lixian, Jiangshan, after the fossil-producing Lixian Village, Jangshan County, saurus (Gr.) dinosaur
Holotype
M1322 in the Zhejiang Natutal Museum. A relatively complete left scapulacoracoid, 5 posterior and mid-dorsal vertebrae, parts of both sides of pubis and ischium, 3 caudal vertebrae and parts of the femur shaft are preserved.
Diagnosis of genus (as for the type speices)
Dorsal neural spines with developed concativity and lamina, margin of lamina thin; cranial convexity on articular surface of dorsal centra strongly developed, articula \\\"ball\\\" nearly hemispherical, ventral surface almost concave (preserved) dorsal ribs apparently distinctly pneumaticized; acromial process od scapula having large proximal expansion, width approximately 150 percent of ilium blade width; scapular glenoid facing medially, coracoid glenoid laterally; scapular glemoid opening with right angle; supracoracoideus fossa large, flat, oval shaped; coracoid foramen located almost at center of corracoid, far from suture connecting scapula; articulations between proximal caudal centra distinctly procoelous (preserved) middle caudal centra mildly procoelous; caudal neural arches located on proximal half of the centrum; absence of pleurocoels in caudal centra. (Tang, Kang, Jin, Wei and Wu , 2001).
