""Oyster"" is a generic name given to a group of shelled mollusks that live in the ocean, feeding on plankton which they filter through their gills.The shells containing high levels of calcium are generally fossilized easily. The oldest known oyster fossil comes from the Ordovician period (490 to 443 million years ago). Despite the approximately half a million years that have passed since then, oysters have not changed. Those oysters that lived 490 million years ago or 150 million years ago are no different from those alive today. This fact completely nullifies the claims of evolution that creatures evolved in stages, in a succession of tiny changes. The fossil record shows that creatures have not gone through any process of evolution and that Almighty God created them.
