| Summary: | Abstract Understanding ancient oceanic conditions becomes fundamentally easier in the Cretaceous due to the plentiful oceanic crust of this age. Coincidentally, the proliferation and radiation of planktonic foraminifera in the Early Cretaceous also allow the direct study of fluctuations in oceanic surface waters for the first time. With this burgeoning of the data base, all post-Jurassic extinction mechanisms have to be in accord with both open-ocean and shelf-sea evidence. |
