The stable isotope record of Cenomanian and Turonian rudists were compared for areas located at low paleolatitudes (Northern Egypt) and middle paleolatitudes (Czech Republic). The oxygen isotope data indicate that the oxygen isotope composition of seawater was not identical for both areas, which complicates estimation of paleotemperature. Rudist generic diversity of both areas was also compared. The Cenomanian and Turonian rudist assemblages from Egypt and the BCB show similar generic diversity, and also display a similar marked diversity decrease across the Cenomanian/Turonian boundary interval. It is important to note that both areas have similar diversity on the generic and partially species level during the Cenomanian and Turonian.
