Collected from the Rushmere Member of the Pliocene Yorktown Formation. Most of these, along with many of the other "clam" type bivalves are extremely crumbly and often fall apart when picked up. This specimen was dug out of the layer and is a great example of the species.
These pectens are very common in the Rushmere Member of the Yorktown Formation in cuts and bluffs along certain portions of the Tar River in North Carolina. Many are extremely worn and even crumble to pieces when handles. Specimens with double valves are not uncommon. This specimen is in exceptional shape. The final picture of the 3 specimens is to illustrate the growth of the species. They are all double valves, and range from 1 /4 inch long to 5 5/8 inch long.
