西藏羌北地区石炭纪■类动物群是笔者等于2004年首次发现的,并将动物群所在层位建立了瓦垄山组,该套地层中产大量的■类化石,种属多,分布连续。经研究,自下而上建立6个■类化石带:(1)Eosta ffella mosquensis带,(2)Millerella-Eostaf fella带,(3)Pseudostaf fella-Eostaf fella带,(4)Pro-fusuliena带,(5)Fusulina-Fusulinella带,(6)Protriticites-Triticites带。该套含竹蜓类化石地层的发现,为研究羌北地区晚古生代构造活动提供了信息,也为研究该区石炭纪地层、古生物、生物古地理、区域性地层划分和对比提供了依据。
The Carboniferous-type fauna in the northern Qiangtang area of Tibet was first discovered by the author in 2004 and the Wawunshan Formation was established in the strata of the fauna. There are a large number of fossils in this set of formations, with many species and continuous distribution. From the bottom up, six fossil zones have been established: (1) Eosta ffella mosquensis zone, (2) Millerella-Eostaf fella zone, (3) Pseudostaf fella-Eostaf fella zone, (4) Pro-fusuliena zone, (5) Fusulina-Fusulinella band, (6) Protriticites-Triticites band. The discovery of bamboo-fossilized fossil strata provides information for the study of Late Paleozoic tectonic activities in the Qiangbei area, and also provides a basis for the study of the stratigraphic, paleontological, paleoclimatic and regional stratigraphic division and contrast in this area.
