Silurian-Devonian boundary events and their influence on cephalopod evolution: evolutionary significance of cephalopod egg size during mass extinctions

Original language description

Diversity evolution of 197 of the latest Ludlow-Lochkovian cephalopod species from Bohemia was analysed and compared with changes in the global carbon cycle in the marine ecosystem. Our results show a distinct relationship between cephalopod species diversity and the global carbon cycle. A progressive increase in ?13C values in marine carbonates from the lochkoviensis Zone to the end of the transgrediens Zone clearly illustrates an increase of bioproductivity in the marine ecosystem. The increase in bioproductivity was probably caused by a shallowing of the upwelling system bringing nutrient-rich water and being triggered by a progressive cooling during the Přídolí and earliest Lochkovian.
