Ammonites (ammonitida) were shelled cephalopod molluscs that lived throughout the world’s oceans during the mesozoic (triassic, jurassic and cretaceous periods) and they were an extremely successful order, as evidenced by the frequency with which their remains are found. Octopus, squid and cuttlefish, the shells are small and internal, or absent.
