2 Polished belemnite fossils
2 Polished belemnite fossils!!!Belemnites are probably the tremendously well known extinct cephalopod after the ammonites. They lived during the Jurassic and Cretaceous periods and are fairly common fossils found throughout the world. They had a hard, internal, cone shaped structure that is often preserved as a fossil though it is not technically a shell. They had 10 arms but unlike contemporary squid these arms had small hooks instead of suckers.
