New discovery of Jurassic dinosaur fossils in Chaya area, Qamdu district, Tibet
-
摘要:
在西藏昌都市察雅地区侏罗纪红层中发现了恐龙化石，主要包括肋骨、椎体等。对其中保存较完整的蜥脚类颈椎、肩胛骨、兽脚类耻骨等进行了形态学描述。虽然目前发现的材料较少，确定种属还存在一定困难，但其丰富了侏罗纪恐龙的地理分布。该地区恐龙化石多处出露，说明恐龙化石相对丰富。对该地区恐龙化石的进一步勘查和研究，有助于进一步了解亚洲地区蜥脚类和兽脚类恐龙的早期演化和分异。
Abstract:The dinosaur fossils were discovered in Jurassic red beds in Chaya area, Qamdu district, Tibet, mainly including ribs, vertebral bodies and so on, and their well preserved cervical vertebrae and scapula and pubis were morphologically described.Despite some difficulties in the attribution of species since few materials have been discovered so far, the discovery enriches the Jurassic dinosaur-bearing localities.Many dinosaur bones have been discovered in this area, indicating that they are relatively abundant.Further exploration and study of dinosaur fossils in the region will help us better understand the early evolution and differentiation of sauropods and theropods in Asia.
