Geologic History

The fossils at East Fork formed during the Ordovician (Late Ordovician).

Millions of years ago, the area that is now Bethel, Ohio was a shallow tropical sea environment. The climate was warm tropical with extensive shallow seas.

As these ancient organisms died, sediments buried and preserved their remains. Over millions of years, geological processes transformed these sediments into the fossil-bearing rocks visible at East Fork today.
