河北陆相侏罗—白垩系火山—沉积地层在燕山地区十分发育并含有较丰富的介形类化石。由于以往系统研究不够,对河北中生代介形类化石资料报道甚少。笔者自1977—1980 年间,在全省侏罗—白垩系地层中共发现介形类化石19个属,78个种,其中有24个新种。这不仅丰富了河北中生代介形类化石资料,而且初步搞清了长山峪群,滦平群介形类化石组合面貌。这对我国北方陆相侏罗—白垩系地层划分对比及时代确定具有重要意义。
The continental Jurassic-Cretaceous volcano-sedimentary strata in Hebei Province are well developed in the Yanshan area and contain abundant ostracods. Due to the lack of systematic research in the past, little is known about the Mesozoic fossil data in Hebei Province. From 1977 to 1980, the author discovered 19 genera and 78 species of Ostracoda fossils in the Jurassic-Cretaceous strata of the province, of which 24 are new species. This not only enriches the Mesozoic fossil data of Mesozoic in Hebei Province, but also initially ascertains the appearance of the fossil assemblages of the Changshan-Yu group and the Luanping Group. This is of great significance to the division and comparison of continental Jurassic-Cretaceous strata in northern China.
