Abstract: The Houldjin Formation was discovered and named by the Third Asiatic Expedition in 1922. Its geological age was first considered as Miocene or later, then varied from Oligocene to Late Eocene because of scarcity of mammalian fossils found in that formation. Since 1985, some additional mammalian fossils have been found. These discoveries have throw more light on its age determination. The micromammalian fossils have already been reported. The large mamma鄄 lian fossils, except paraceratherines, are described here.
摘要: 记述了近年来采自二连浩特附近呼尔井组中的大哺乳动物化石:Hyaenodon sp.,Metatitan sp., Aprotodon lanzhouensis, Symphysorrhachis? sp., Cadurcodon houldjinensissp. nov. 和Entelodon gobiensis。新种Cadurcodon houldjinensis 的主要特征是:个体大,齿冠高,上前臼齿外壁无明显的肋;上臼齿前附尖和前尖肋窄而紧靠;下臼齿外中沟弱;内齿带高,封闭内谷;具外齿带;m1 下三角座稍短于下跟座。Matthew 和Granger (1923)所记述之Cadurcotherium sp. 和Cadurcotherium? sp. 标本被分别归入Cadurcodon houldjinensis 和C. ardynensis。对呼尔井组迄今所发现的哺乳动物化石的分析表明,该组的时代应为晚始新世。
