Title: Acroteathis Subquadratus
Item Name: Fossil


Several examples of fossil belemnites (Acroteathis Subquadratus), black/grey. From Speeton clay. Belemnites were small tentacled sea creatures (a member of the cephalopod group), which lived during the Mesozoic period (about 248-66 million years ago). In antiquity these fossils were popularly known as "thunderbolts", since it was thought they had been flung out of the sky during thunderstorms. The long, bullet-shaped shell of the creatures was made of calcite (calcium carbonate).
