Fossilized clams can be hundreds of thousands to millions of years old, depending on the geological age of the rock layer in which they are found. Some fossilized clams date back to the Mesozoic Era, which lasted from about 252 to 66 million years ago. The specific age of a fossilized clam can often be determined through radiometric dating and stratigraphic analysis.
