Description
West of Reno, Nevada
Diatomaceous Earth is the result of dried, compact siliceous diatoms. Another name for this type of fossil is Diatomite. Because of their requirement of light for photosynthesis, Diatoms are confined to shallow water in marine and freshwater environments. They can be found in polar regions, in which they are important food chain organisms and provide nutrients to tiny crustations like krill and shrimp. Diatoms are usually the first to take over surfaces like shells, rocks, polar ice, and more.
