详细描述了采自新疆准噶尔盆地北缘铁尔斯哈巴合陡坎晚渐新世一刺猬的耳区岩骨结构。晚渐新世地层为该地区的新发现，描述的刺猬岩骨有以下特征：岬内侧面具岩骨前鼓突，腹面具岬动脉与镫骨动脉留下的沟痕，岩骨后鼓突发育并掩盖蜗窗，弓形小窝深大，乳状小突发育。岩骨的某些特殊特征可以用来鉴定某些哺乳动物类群，因此具有系统分类及生物地层意义。
A detailed description of the structure of the petrous bone in the ear zone of the Neoproterozoic hedgehog collected from the Stewart ridge of the Earlshaba in the northern margin of the Junggar Basin in Xinjiang is described in detail. Late Oligocene strata are the new discoveries in the area and describe the following characteristics of the hedgehog bone: cavernous anterior promontory of the cape, ventral cavernous and tarsal artery trenches, Education and cover the snail window, bow-shaped deep pit, small bursa. Some special characteristics of the rock bone can be used to identify certain mammalian groups, and therefore have systematic classification and bio-geological significance.
