Carbon and oxygen stable isotopes of selected Cenomanian and Turonian rudists from Egypt and Czech Republic, and a note on changes in rudist diversity

Popis výsledku v původním jazyce

The stable isotope record and diversity of Cenomanian and Turonian rudists were compared for areas located at low paleolatitudes (10 degrees N - Northern Egypt; 5 samples; 13 analyses) and middle paleolatitudes (35 degrees N - Czech Republic, Bohemian Cretaceous Basin, BCB; 4 samples; 7 analyses). The oxygen isotope data indicate that the delta(18)O value of seawater was not identical for both areas. Moreover, local variations in seawater delta(18)O in the range of at least +/- 1 parts per thousand areprobable in the shallow water near-shore environment where the rudists lived. Supposing a value of -1 parts per thousand VSMOW for contemporaneous seawater, the paleotemperature can be calculated as being between 24.5 and 31.5 degrees C for the Late Cenomanian and between 32.9 and 34.7 degrees C for the Early Turonian in the BCB. The delta(18)O seawater value for the northern part of Egypt was probably slightly lower. Calculation using a seawater value of -1.5 parts per thousand VSMOW gi
