| 摘 要： | 云杉孢粉组合与披毛犀,这两类晚更新世的重要化石,过去在天津还没发现和正式报道过。近年来,不但已在天津找到,而且还发现它们同层共存于一个钻孔之中,这种同孔同层共存的事例,在我国还是首次发现,对研究该化石本身及天津当时的地质地理具有重要意义。

| Abstract: | The Picca spore-pollen complex of the late pleistocene was discovered and the Coelod.antiquitalis was detected in Tianjin city in 1978 (It was located in a bore hole at the depth of 42.5 meters and a Picea pollen complex at 42.4-40 meters).Their geological age is estimated to be about 40,000-10,000 or 22.800-22,000 Y.B.P..The Picea-Coelodonta fossil complex indicates that the air temperature at that time was about 11℃ lower than that of today and marine regression had occurred.But there were several reversed warm epochs during the regression period.For instance,an increase of Carpinus pollens of the broad leaf trees,24,400 and 22,900 Y.B.P.was identified.Perhaps the warm epoch implies a regional transgression of the sea. |
