Belemnites are an extinct group of marine cephalopods which are similar to modern cuttlefish and squid. They first appeared in the Devonian period - 416 million years ago and became extinct during Cretaceous times.
They were cigar shaped, had an ink-sac (like cuttlefish and squid) but no tentacles, instead they had 10 arms which had small hooks for grabbing prey, such as fish, which they ate with beak shaped jaw. Their shell sizes ranged from 60cm to about 1cm in length. Therefore, the overall length of the largest would have probably been about 3 meters.
