Title: B Minimus
Item Name: Fossil


Small belemnite (B Minimus) embedded in a piece of rock. From red chalk at Speeton. 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).

Materials: chalk; stone
