Diatomaceous Earth, also known as DE and Fossil Shell Flour, is the fossilized remains of hard shelled, one celled plants called Diatoms. These plants lived in the oceans and other bodies of water that once covered the western part of the United States. The Diatoms served as a food source for aquatic life. When they died, their shells drifted to the bottom of the body of water. Millions of years later, huge deposits of Diatomaceous Earth were discovered after the water receded.
