摘要
本文记述了内蒙古二连盆地“马捷茨营地”(Camp Margetts)地区中始新世阿山头组产出的一种古双尖齿兽:Archaeoryctes borealis sp. nov.。该种为中国北方及中亚一带已知双尖齿兽科中形态最为原始、出现时代最早的分子。它使中国南方早期的双尖齿兽科成员与北方较晚期的成员建立了某种关系。文中对与该种产出地点及地层有关的问题进行了讨论。
A small didymoconid, Archaeoryctes borealaa sp. nov,is described. The specimen wascollected from the Middle ocene Arshanto Formation at Camp Margetts area, Nei Mongol in1930 by the Central Asiatic Expedition Team from the American Museum of Natural History(AMNH). The new species represents the earliest and most primitive didymoconids known in
the central Asiatic area. It links the even earlier didymoconids from south China to theirlater central Asiatic members. iscussion about the locality and stratigraphy associated tothe specimen is presented, which is developed‘mainly on the uthor's field observation in July,1988, and the field notes made by the Central Asiatic Expedition. I am grateful to R. -j. Zhai, C.一Li, T. Qi and J. -j. Zheng- (IVPP) for arranging thefield work and introducing me the stratigraphy of Erhlien basin, Nei Mongol. Particularly, Ithank J. Ye and Y. -q. Wang (IVPP) for their help during the field work in Nei Mongol. I
also thank Drs. M. C. McKenna and M. J. Novacek (AMNH) for encouraging and support-ing me throughout the course of this study and for permitting the study of the specimens undertheir care. This subject is supported by a faculty fellowship from Columbia University and bythe James Carter Memorial Fund (AMNH)
