1997和 1 998年的野外工作期间 ,在新疆准噶尔盆地北缘铁尔斯哈巴合中中新世哈拉玛盖组的底部第二砂层中发现了 4枚上猿牙齿。两枚显然是属于同一个体的左m2和m3发现于 980 1 7地点 ,地理坐标为 46°39.997′N ,88°30 .41 2′E。另一枚左下第一门齿和左上第四前臼齿产自该地点附近的同一砂层中。这是在中国境内、也是亚洲的第二个上猿化石地点。该 4枚牙齿中 ,下门齿可能与m2、m3属同一个种。m2刚开始经受磨蚀 ,m3则刚萌出齿槽。它们不同于所有已知种 (P .zhanxiangi、P .vindobonensis、P .antiquus、P .platyodon和P .priensis)的最明显的特征是在唇侧有一个很深的、间于下原尖和下次尖的漏斗状小坑。该坑由前次脊 (prehypocristid)、下次尖前方的斜脊的唇侧分支和沿下原尖唇侧壁向下延伸的一条脊所围成。此外 ,m3稍短于m2。在其他形态特征方面 ,新疆的种又以m2和m3尺寸较小、齿尖较低、齿脊较锐、近中凹和远中凹发育、釉面褶皱和唇侧齿带很发育而不同于我国宁夏同心的Pliopithecuszhanxiangi;以m2和m3的冠面较短宽且有很发育的上猿三角与P .vindobonensis区分 ;其m2和m3的尺寸明显大于P .antiquus。但在尺寸和其他形态上与P .platyodon很相似。铁尔斯哈巴合的m2、m3和下门齿应代表上猿属内的一个新?
During the field work in 1997 and 1998, four ape-like teeth were found in the second sand layer at the bottom of the Miocene Halamage Formation in the northern Algeciras of the Junggar Basin, Xinjiang. Two of the two apparent sm 2m and m3 belonging to the same individual were found at 980 1 7 with geographic coordinates of 46 ° 39.997’N and 88 ° 30.41 2’E. The other lower left first incisor and the upper left fourth premolar came from the same sand layer near the site. This is the second ape fossil site in China and Asia. The 4 teeth, the lower incisors may be m2, m3 are the same species. m2 just started to withstand abrasion, m3 just erupted alveolar. They are distinguished from the known features of all known species (P. zhanxiangi, P. vindobonensis, P. antiquus, P. platyodon and P. priensis) by the fact that they have a deep, labial apical and inferior Tiny funnel-shaped pits. The pits are surrounded by a prehypocristid, a labial branch of the apical ridge at the next apical ridge, and a ridge extending downwardly along the sidewall of the apical apical lip. In addition, m3 is slightly shorter than m2. In other morphological characteristics, the species of Xinjiang are smaller in m2 and m3, with lower tip, more sharply toothed ridges, nearly subdural and far-concavely developed, and the glazed folds and labial toothed belts develop rather differently China’s Ningxia concentric Pliopithecuszhanxiangi; with m2 and m3 of the crown surface shorter and wide and well-developed ape triangle and P. vindobonensis distinguish; its m2 and m3 size was significantly greater than P. Antiquus. But is similar in size and other morphology to P.platyodon. Irons Happer’s m2, m3 and lower incisors should represent a new within the genus Sargassum?
