DISCOVERY OF OSTRACODA IN MANGCHUAN FORMATION, LUOYANG BASIN, HENAN PROVINCE AND DISCUSSIONS ON ASSEMBLAGES OF EARLY EOCENE OSTRACODA IN CHINA

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.
