Abstract: Some fossil insectivores and chiropteres were collected from the Upper Eocene of Nei Mongol. They represent the first records of their kinds in Late Eocene in Nei Mongol. The discovery has not only expanded the distribution of insectivores and chiropteres in Asia, added new elements to the Late Eocene fauna of Nei Mongol, but also provided new information on paleoenvironment of this area.
摘要: 描述了2种食虫类化石(Antolechinos neimeongolensis gen. et sp nov., Ictopidium lechei), 1刺猬科(属、种未定)(Erinaceidae gen. et sp. indet.)和2类属、种未定的蝙蝠化石(Microchiroptera gen. et sp indet. A和B)。Anatolechinos gen. nov. 的主要特点是:个体较小;具p1/1; 颊齿齿冠低,主齿尖低钝;P3-M3前附尖低小;P3-M2的后附尖脊短而低,次尖与后齿带有棱相连,舌侧无齿带;P3-4舌叶较长,次尖大;P3次尖与原尖有棱相连;M1原小尖和后小尖的前、后棱均较短,次尖前棱很弱;M3后小尖后棱长;下臼齿下内尖棱短等。认为原归入齿鼩猬的Tupaiodon huadianensis也应归入Anatolechinos新属。新种A.neimongolensis与A.huadianensis的主要区别是其个体较小,齿冠稍高,p4无下前边尖,外齿带弱而不完全等。将Anatolechinos归入Erinaceidae的Tupaiodontinae。讨论了内蒙古中-西部在晚始新世的古生态环境。
