| The marine biostratigraphy is based upon microfaunas and floras, notably planktonic foraminifera and radiolaria. |
| The team did not limit themselves to foraminifera but used other planktonic groups such as the coccoliths and radiolaria. |
| The Gracisce packstones contain a rich foraminiferal assemblage, composed of larger and planktonic foraminifera along with authigenic glauconite. |
| The remaining carbonate bioclasts are exclusively calcitic echinoid spines, rare foraminifera, molluscs and bryozoan fragments. |
| The foraminifera analysed in this study are generally well preserved and not recrystallized. |
| Also, other microfossils such as diatoms, radiolaria, and planktonic and benthic foraminifera are useful in certain parts of the Palaeocene. |
