This is a very nice association fossil. It is a fine specimen of a large gastropod and two Scaphites ammonites from the Cretaceous of South Dakota. This type of ammonite has faint ribbing and a somewhat squared keel. These features are very clearly defined on these specimens. But the rarest feature of this fossil is the large gastropod preserved on the plate. The gastropod is very distinct and extremely 3-D. The entire block is just covered with bivalves, ammonite parts, and other fossils. This is a very cool association fossil from the Black Hills.
