本文根据洛阳盆地蟒川组介形类,讨论了我国早始新世Cypris henanensis-Eucypris subtrian-gularis-Limnocythere hubeiens组合(简称C-E-L组合)的分布、地质时代和古生态,提出C-E-L介形类组合是在我国广泛分布的早始新世非海相介形类动物群,它在洛阳盆地的发现为研究我国早始新世介形类动物群增添了新资料,也为我国陆相盆地下始新统的划分、对比提供了依据。

Based on the discovery of Ostracoda in Mangchuan Formation of Luoyang Basin,Henan Province,the distribution,time and paleoecology of Early Eocene assemblage for Cypris henanensis-Eucypris subtriangularis-Limnocythere hubeiensis (C-E-L assemblage) have been discussed in this paper.It is proposed that C-E-L Ostracoda assemblage is a non-marine Early Eocene fauna widespreading throughout China.This finding in Luoyang Basin will provide new data for the studies on Early Eocene Ostracoda fauna in China and also provide a basis for the division and correlation of Lower Eocene sequences of Chinese non-marine basins.
