| To avoid confusion, microfossil assemblages were used to classify the chalk marl. |
| More-recent seismic and microfossil studies have suggested that the seafloor never was completely dry. |
| Larger animals are too scarce in the fossil record for good statistics, so paleontologists have analyzed microfossil extinctions. |
| Once they have sketched the outlines of the basic chronology, geochemistry and geography, the rest will probably fall, microfossil by microfossil. |
| An example of a dinocyst, a microfossil that is often found in marine sedimentary rocks. |
| Micropalaeontology is the study of microfossils, a microfossil being any fossil that is best studied by means of a microscope. |
