Grouped here are a collection (colony) of shells that resemble the familiar scallops both in shape and in having radiating grooves and ridges on the surface.

The example here was found at Monroe Bay, Westmoreland County, Virginia along the Potomac River. These organisms lived in the Devonian Period making them 345 million to 395 million years old...
