The Late Cenomanian Anoxic Event; implications for foraminiferal evolution
Abstract
This study investigates the effect of the late Cenomanian Oceanic Anoxic Event (OAE) on the planktonic and benthonic foraminifera. On the former, the OAE was the cause of major extinctions within the population, the return to pre-OAE oxygen levels permitting recolonization of the vacated niches. On the latter, the OAE caused extinctions but resulted in a low oxygen tolerant fauna which slowly evolved into the vacated niches on the post-OAE recovery of oxygen levels. The changes in the foraminiferal populations have been integrated with changes in other marine organisms through the late Cenomanian.
