| The remaining carbonate bioclasts are exclusively calcitic echinoid spines, rare foraminifera, molluscs and bryozoan fragments. |
| Also, other microfossils such as diatoms, radiolaria, and planktonic and benthic foraminifera are useful in certain parts of the Palaeocene. |
| From such studies as those of Be and Spero and Wilde, we know that foraminifera sometimes regenerate their tests after injury. |
| The marine biostratigraphy is based upon microfaunas and floras, notably planktonic foraminifera and radiolaria. |
| Based on gastropods, bivalves, and planktonic foraminifera, Kilmer assigned this formation to the Turonian. |
| The succession was sampled for biostratigraphic analysis using foraminifera and nannoplankton. |
