| Abstract: | The Upper Pleistocene and the Holocene of Aigion have delivered an abundant microfauna with 35 ostracode species. The Pleistocene from Aigion borehole generally provides Ostracodes from oligohaline environment with Cyprideis torosa, Candona angulata and Tyrrhenocythere amnicola while, in the Holocene, marine infralittoral species dominate with Cytheridea neapolitana, Carinocythereis whitei, Loxoconcha ovulata and Cytherois frequens. The marine sedimentation occurred at depth from some meters to some tens of meters. In the Aghios Constantinos section, the lagoonal marls are characterised by Euxinocythere schuldtae and a dwarf species of Xestoleberis. Then, a drastic environmental change occurs around the Pleistocene-Holocene boundary and presumably affected the whole Corinth gulf. |
