Silicoflagellates are another group of [http://www.thefreedictionary.com/planktonic planktonic] [http://www.merriam-webster.com/medical/photosynthesis photosynthesizing] marine [http://www.thefreedictionary.com/planktonic 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 upper 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]].
