1977年,北方槽区古生代地层会议之后,《地层学杂志》(1979年,3卷3期)发表了“天山—兴安区古生代地层研究新进展”(以下简称“进展”)一文,提出了一些新颖的见解,反映了我国当前北方槽区地层古生物研究的水平。对“进展”一文提出的泥盆纪时,北方槽区“实为介于旧世界区和阿伯拉阡区之间的一个独立生物地理区”的论断,笔者认为有商榷的必要。因为它涉及到生物地层学研究的一些概念问题。 In 1977, after the Paleozoic stratigraphic conference in the northern slot area, the article “Advances in Paleozoic Stratigraphy of Tianshan-Xing’an District” (“Progress”) was published by Stratigraphy Magazine (1979, Volume 3, Issue 3) The novel opinion reflects the level of paleontological research in the current northern trough area in China. At the time of the Devonian proposed by Progress, the northern trough area was actually an independent biogeographic area between the old and the Aberamian areas. I think there is a need for discussion. Because it involves some conceptual issues of biostratigraphic research.
