Locally sourced from teh North Yorkshire seaside Town of whitby, Belemnites were animals that lived in the sea. They are now extinct. Their name is derived from belemnon (Greek) meaning a dart. A fossil belemnite is usually the guard, the back part of the shell, and this does look like a dart or bullet.
Around at the time of the Dinosaurs, Belemnites were cephalopods. Living cephalopods include octopuses, cuttlefish, squid and nautiloids. Extinct cephalopods include ammonites.
Fun Fact: The belemnite is the state fossil of Delaware in the USA!
