Summary[edit]
DescriptionZigong Dinosaur Museum Shunosaurus tail club.jpg |
English: Tail club of Shunosaurus lii.
Symtemtic position: Cetiosauridae, Sauropodomorpha, Saurischia. Locality: Dashanpu, Zigong, Sichuan, China. Age: Middle Jurassic (about 160 million years ago). This is a well-preserved tail club of Shunosaurus lii fused by several caudal vertabrae at the end of the tail. It is the first discovery of tail clubs of sauropod dinosaurs in the world. It has not only changed the traditional view of sauropods having no positive defense ability, but also provided imporiant evidence for sauropods being land-living animals.中文:李氏蜀龙尾锤
分类:蜥臀目 蜥脚亚目 妖龙科 产地:自贡大山铺 时代:中侏罗世(约1.6亿年前) 这是一个保存完整的李氏蜀龙尾锤,由末端几个尾椎相互愈合膨大而形成。这是世界上首次发现的蜥脚类恐龙尾锤,改变了原来蜥脚类恐龙不具备主动防御能力的传统观点,同时也为蜥脚类恐龙的陆生生活提供了重要证据。 |
