摘要/Abstract

摘要： 近年来在山西省境内沿黄河一带采集到一些新的四足动物化石。在临县白道峪铜川组一段产出的化石中，至少有一种副肯氏兽和一种新的中国肯氏兽——白道峪中国肯氏兽(Sinokannemeyeria baidaoyuensis sp. nov.)。新种以其前额骨向前延伸到达鼻孔后凹一线的特征区别于其他中国肯氏兽。这一材料的长牙未被前颌骨完全包裹，可能是不正常发育所致。在柳林的二马营组地层中识别出不同于中国肯氏兽和副肯氏兽的第三个肯氏兽属。这些新发现增加了中国肯氏兽－山西鳄组合带的组分以及时代延限。

Abstract: Recently, some new tetrapod fossils were collected alongthe Yellow River in Shanxi Province. From the Member I of the Tongchuan Formation at Baidaoyu in Linxian County, at least one species of Parakannemeyeria, and one new species ofSinokannemeyeria, S. baidaoyuensis, are identified. The new species is characterized by prefrontal anterior extension level to posterior margin of postnarial excavation. From the Ermaying Formation inLinxian County, a third kannemeyeriid genus is identified for theSinokannemeyeria-Shansisuchus Assemblage. The new findings increase the content and time extension of the Sinokannemeyeria-Shansisuchus Assemblage.
