记述的巨龙科Titanosauridae一新属种———礼贤江山龙 (Jiangshanosauruslixianensisgen .etsp .nov .)产自浙江江山的金华组下部 ,地质时代为早白垩世晚期的Albian期。化石保存了部分头后骨骼 ,经过与晚侏罗世至晚白垩世蜥脚类化石的对比表明 ,新属的尾椎特征与巨龙科较为相似 ,肩胛骨、乌喙骨与巨龙科中的阿拉蒙龙属 (Alamosaurus)最为接近 ,但新属的前部尾椎较大 ,前凹后突的程度较不明显。新属种保存的背椎和中部尾椎的部分特征与我国晚侏罗世马门溪龙科也很相近。新属种是在我国首次记述的巨龙科化石 ,为研究白垩纪蜥脚类恐龙在我国的演化分布提供了新的材料。
Described a new genus Titanosauridae a species --- Lixian Jiangshanosaurus (Jiangshanosauruslixianensisgen.etsp. Nov.) Produced in Zhejiang Jiangshan lower Jinhua Group, the geological age of the early Cretaceous Albian period. The fossil has preserved some of the posterior head bones. After comparing with the sauropod from the Late Jurassic to the Late Cretaceous, it has been shown that the new member’s caudal features are similar to those of the Jurassicidae. The scapula, Alamosaurus most closely, but the new genus anterior caudal large, anterior concave and convex degree of less obvious. Some of the features of the dorsal vertebrae and central caudal vertebra preserved by the new species are also similar to those of the Late Jurassic Manchurian Archipelago in China. The new species is the first recorded in our country dragon fossils, to study the evolution of Cretaceous sauropod dinosaur in our country provides a new material.
