FOSSIL BIVALVE
Good condition and size Fossil Bivalve. Clams and their relatives (oysters, scallops, and mussels) are often called bivalves (or bivalved mollusks) because their shell is composed of two parts called valves. Bivalves have a long history. Their fossils first appear in rocks that date to the middle of the Cambrian Period, about 510 million years ago.
