Belemnitella americana (Morton) Belemnites belong to a diverse group of cephalopods which include the squid, cuttlefish and octopus, they are characterized by an internally chambered shell known as a guard. The rostrum or guard is found the most often and possesses a distinctive slit at its ventral surface and a ridge on the dorsal surface. The rostrum served as a counter-weight to the buoyancy provided by the chambered shell and also for protection of that delicate shell. Belemnitella mucronata is usually fairly long and straight with a gradual taper to the posterior of the guard, it is characterized by a sharp tip called a mucron.The guards are often 2 - 4 inches long and found poking out of the smaller pebbles on the beach.
