Calcite Crystals

Date: Cretaceous Period (145-65 million years old)

 

Description: These calcite crystals were found in the limestone deposits of Stone State Park. Calcite, or calcium carbonate, is a major component of limestone and is largely made up fossilized sea shells. These fossilized shells become crystalized deep in the earth and form the crystals seen in this example.
