A fossilized clam is a shell from a clam that lived a long time ago. It helps us learn about ocean life in the past!
The Fossilized Clam is typically a grey, tan, or brown stony impression of a bivalve shell. It features distinct concentric growth lines and a symmetrical, often oval or rounded shape, visibly different from fossilized snails which have a coiled structure.
