Abstract
Various methods of ostracod analysis with reference to paleobathymetric and paleotemperature reconstruction are considered in detail, using Callovian–Lower Oxfordian ostracod assemblages from the Mikhailovtsement reference section (Ryazan Region) as an example. Based on generalization of the data obtained by different methods, seven transgressive–regressive events are reconstructed, five of which had a pan-European scale and were accompanied by the intensified boreal effect. For the Upper Callovian of the East European Platform, ostracod index species of paleotemperatures, paleoeutrophication, and paleodepths on the upper subtidal depths are recognized for the first time.
