1983年程政武和庞其清在山西省天镇县赵家沟康代梁灰泉堡组中首次发现恐龙化石后,分别于1989年和1991~1994年在该地挖掘恐龙化石期间,于山西天镇及河北阳原一带的灰泉堡组中又发现了较丰富的介形虫、轮藻和少量孢粉化石。本文首次对该地区轮藻植物群的发现及其产出层位、组合特征和时代等问题作一简要报道和讨论。在此对河北地质学院姚义川、王德文、杨光礼、刘志鸿和冯刚等同学在实习期间采集和分析部分样品表示感谢。
In 1983, Cheng Zhengwu and Pang Qiqing discovered the dinosaur fossils in Kangde Liangquanquan Formation, Zhaojiagou, Tianzhen County, Shanxi Province. After excavating the dinosaur fossils at that place in 1989 and 1991-1994 respectively, In the area of Yangquan, Hebei Province, more abundant ostracods, charophytes and a few sporo-pollen fossils were found in the group of Ash-Fort. This article first makes a brief report and discussion on the discovery of Charophyllidae flora and its output strata, combination characteristics and the times in this area. Here I would like to express my gratitude to Yao Yichuan, Wang Dewen, Yang Guangli, Liu Zhihong and Feng Gang from Hebei Geological College for collecting and analyzing some samples during internship.
