Mollusk Beach, Virginia
Detailed Description
In the middle part of the Pliocene, about 3 million years ago, sea level was about 25 meters higher than it is today. Seashells that were then underwater are now exposed high in the bluffs on either side of the James River. These large fossil shells, mostly Chesapectin, have eroded out of the bluffs and cover the beaches near Smithfield, Virginia.
