摘要

摘要日本西南部九州岛的下白垩纪Kanmon群中迄今为止报道的最大的单一骨元素碎片被描述。该标本的外侧表面有窝状孔和透镜状孔，内室大小不一。主要根据这种气动结构，鉴定为雷龙状蜥脚类恐龙的颈椎。这个标本代表了从卡门群中描述的第一个泰坦龙。

Description of a Titanosauriform (Sauropoda, Dinosauria) Cervical Vertebra from the Lower Cretaceous Kanmon Group, Southwestern Japan

Abstract. A fragmentary and the largest single bone element from the Lower Cretaceous Kanmon Group in Kyushu Island, southwestern Japan reported yet to date is described. This specimen has a fossa and lenticular foramen on its lateral surface and internal chambers of both large and small sizes. It was identified as the cervical vertebra of a titanosauriform sauropod dinosaur mainly based on such pneumatic structure. This specimen represents the first titanosauriform to be described from the Kanmon Group.

期刊介绍： Paleonotological Research (PR) is a quarterly, peer-reviewed international journal, which focuses on original contributions primarily in the area of paleontology but also covering a wide range of allied sciences. It has been published since 1997 as a successor to the former journal Transactions and Proceedings of the Palaeontological Society of Japan. The emphasis of contributions will include global and local perspectives, and contents can cover all ages (Precambrian to the Quaternary, including the present time).
