STATE STONE
PETRIFIED WOOD
Designated as State Stone in 1976.
Petrified wood is a plant fossil in which the cells of the wood have been replaced by minerals, usually silica. Fossilized wood comes in a variety of colors, and can be sectioned and polished to make the original structure more apparent. Often times, one can still see the original tree rings, cell walls and even the texture of the tree’s bark.

This soil was collected in the early 1900's for the Department of Geology and Geography (now the Department of Geosciences) at Mississippi State. The soil derived from wind-blown glacial silt and is Pleistocene in age.
