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. Devonochonetes are true bivalves; however, the belief is there was an appendage at the base of the shell to keep the organism upright within a colony. 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...

Busycon is a genus of very large edible sea snails, marine gastropod mollusks, in the family Buccinidae. These snails are commonly known in the U.S. as whelks or Busycon whelks.

These fossils date to the Cretaceous Period of the Mesozoic Era (65 million to 136 million years ago)...
