摘要
华北二叠纪的二齿兽类记录很少。从2009年开始在内蒙古大青山地区脑包沟组中采集到大量的二齿兽类化石,从中可以鉴别出7个形态类型,它们可能代表了7个物种:其中2个与边缘大青山兽(Daqingshanodon limbus)密切相关,3或4个与新疆吉木萨尔兽(Jimusaria sinkianensis)关系密切,1个可能与吐鲁番兽(Turfanodon)关系密切。研究表明华北的二齿兽类在种级也具有很高的多样性。
The Permian dicynodont records were previously rare in North China,but many dicynodont specimens have been collected from the Naobaogou Formation in Daqingshan area,Nei Mongol since 2009.Among these specimens,seven morphotypes have been identified,and they may represent seven different species:two of them are closely related to Daqingshanodon limbus,three or four are closely related to Jimusaria sinkianensis,and one may be closely related to Turfanodon.This study shows the dicynodonts also have a high diversity at the species level in North China.
