Dinoflagellate fossils

Micrograph images of Two fossil dinoflagellates in a rock

The presence of these two fossil dinoflagellates in a rock can help date it to the late Cretaceous. The fossils are only about 200 µm long.

These microfossils helped scientists use fossil correlation to date dinosaurs that once lived in New Zealand.
