Silicoflagellates are another group of planktonic photosynthesizing marine protists; they commonly occur with diatoms. Silicoflagellates range in age from Cretaceous to Holocene. Although not as common as diatoms, they are useful time indicators, particularly in the late Cenozoic. As a group, they were much more abundant during the early and middle Cenozoic than today. They have been used to estimate marine paleotemperatures in the late Tertiary and Quaternary.
