What Are Bi-Valves?

Bi-Valves were molluscs, like clams and oysters, which first swam the seas 500 million years ago: Bivalve Fossils can thus also be called Oyster Fossils, Oyster Shell Fossils, and Clam Fossils. 

The Bivalve Molluscs Class or Bivalvia Molluscs Class includes a range of shelled molluscs that show a shell in two parts linked with a hinge, such as clams, oysters, scallops and mussels. 

Bivalve Fossils formed from the natural shells of real Bi-Valves that lived many millions of years ago: over time, the natural shell of the Bi-Valve was fossilised by mineral replacements, leading to the Bi-Valve Fossils we are discovering today.
