Sauropoda is one of the most diverse and geographically widespread clades of herbivorous dinosaurs, and until now, their remains have now been recovered from all continental landmasses except Antarctica. We report the first record of a sauropod dinosaur from Antarctica, represented by an incomplete caudal vertebra from the Late Cretaceous of James Ross Island. The size and morphology of the specimen allows its identification as a lithostrotian titanosaur. Our finding indicates that advanced titanosaurs achieved a global distribution at least by the Late Cretaceous.
蜥脚类恐龙是食草恐龙中种类最多、地理分布最广的类群之一，到目前为止，除南极洲外，在其他各大洲都发现过它们的化石遗迹。我们报告了南极洲蜥脚类恐龙的首个记录，该记录以詹姆斯罗斯岛晚白垩世的一块不完整尾椎骨为代表。根据标本的大小和形态，可将其鉴定为石颈泰坦巨龙类。我们的发现表明，至少在晚白垩世时期，进步的泰坦巨龙类已经实现了全球分布。
