"Scaphites (Greek skafh, "a boat or anything dug or scooped out") is a genus of extinct cephalopod belonging to the family of heteromorph ammonites (suborder Ancyloceratina). They were a widespread genus that thrived during the Cretaceous period.
Scaphites generally have a chambered, boat-shaped shell. The initial part (juvenile stage) of the shell is generally more or less involute (tightly-coiled) and compressed, giving no hint of the heteromorphic shell form yet to come. The terminal part (adult stage) is much shorter, erect, and bends over the older shell like a hook. They have transverse, branching ribs with tubercles (small bumps) along the venter."
