| 摘 要： | Taatsiin Gol和Taatsiin Tsagaan Nuur地区的渐新世沉积序列具有重要的地层学意义:这里出露的三达河组和Loh组沉积含有多个化石层和玄武岩夹层。在蒙古-奥地利合作项目中,从研究区域的33个剖面/化石地点的85个化石层中采集了289种化石(11种腹足类、2种两栖类、9种爬行类和267种哺乳类)。本文提供了所有地点的完整哺乳动物清单,并结合大、小哺乳动物的新资料,对蒙古非正式的生物带A,B,C和C1进行了更新。40Ar/39Ar测年给出了至少两组玄武岩年龄:早渐新世玄武岩I组大约31.5Ma,晚渐新世玄武岩II组大约28Ma。它们可以用作渐新世哺乳动物地层学的年代校正点。从早渐新世至晚渐新世,哺乳动物群发生了显著的变化,包括晚渐新世种数的明显减少。这种趋势在肉齿类、食肉类和反刍类中最为突出。 |

| Abstract: | The Oligocene sedimentary sequence of the Taatsiin Gol and Taatsiin Tsagaan Nuur area is of unique stratigraphic importance:here,the exposed sediments of the Hsanda Gol and the Loh Formations display multiple fossil horizons and interbedded basalt layers.In the frame of a Mongolian-Austrian project,289 fossil taxa(11 Gastropoda,2 Amphibia,9 Reptilia and 267 Mammalia)were collected from 85 fossil horizons of 33 sections/fossil sites of the study area.The taxa were identified by an international team of speci... |
