Stable Isotope Composition of Bryozoan Skeletons from Podbřežice (Middle Miocene, Central Paratethys, South Moravia, Czech Republic).

Original language description

The Middle Miocene exposure at Podbřežice (Czech Republic) was analyzed for C and O stable isotopes, including 21 whole rock samples, 98 samples of eight bryozoan species (3 Cyclostomatous and 5 Cheilostomatous) and 19 samples of foraminifer Amphistegina. Post-depositional processes (mainly recrystallization) changed the stable isotopic composition of the whole rock samples. The delta13C values of the bryozoans vary between 0 to 1.7. Two bryozoan groups can be distinguished based on different delta18O values: cyclostomatous bryozoans yield lower values than the cheilostomatous ones. The values shown by foraminiferal tests are closer to the cyclostomatous bryozoans. In contrast, the calculated paleotemperatures for cheilostomatous bryozoans correspond to published paleotemperature data from other taxa from the study area. We are unable to recognize whether the difference among the cheilostomatous and cyclostomatous genera is due to the skeletal ultrastructures, diagenesis, or vital effe
