Claria Clam Fossil with Calcite Crystals

This auction features a large and attractive gastropod fossil (prehistoric clam) named Claria from the renown Pierre Shale formation of western Canada. It was living during the same time as many dinosaurs, in the late Cretaceous, about 75 million years ago. On the same hard shale matrix is a beautiful pocket of white calcite crystals, which are much more sparkly in person than appears in the photo. This lovely fossil would make a great addition to any fossil collection or cool gift.
