Consequences of the cretaceous/paleogene mass extinction for marine ecosystems

Article Abstract:

A study on the consequences of the cretaceous/paleogene mass extinction for marine ecosystems is presented. The extent and timing of marine biogeochemical recovery from the end-crustaceous event is ultimately dependent on the extent and timing of open-ocean ecosystem recovery, which might in turn have created new evolutionary opportunities for a diverse array of marine organisms.
