摘要
近年来 ,古生物工作者在鸡西群城子河组及其相当地层的生物化石研究方面取得了巨大的进展。在总结这些新的材料的基础上 ,通过与国外的化石组合进行对比 ,从海相双壳类、植物、孢粉及海相沟鞭藻化石等多方面的证据 ,尤其是根据 Thracia rotundata、Vectianella、Pseudaphrodina ricordeana等欧洲 Aptian阶重要的双壳类化石、被子植物及三沟类被子植物花粉的出现 ,城子河组的时代应为 Aptian期 -
In recent years, striking progresses have been made in the fossil research of the Chengzihe Formation and the equivalent strata. By means of international correlating with fossil assemblages, this paper discusses the age of the Chengzihe Formation on the basis of bivalves, plants, palynoflora and dinoflagellates. Based on the occurrence of angiosperm, tricolpate pollen and some important Aptian bivalve representatives of Europe, such as Thracia rotundata (J. de C. Sowerby), Vectianella, Pseudaphrodina ricordeana (d'Orbigny) in the Chengzihe Formation, the author regards the Chengzihe Formation to be of Aptian—early Albian age.
