Belemnites

Belemnites were animals that lived in the sea. They are now extinct. Their name is derived from belemnon (Greek) meaning a dart. A fossil belemite is usually the guard, the back part of the shell, and this does look like a dart or bullet.

Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Subclass: Coleoidea
Belemnites were cephalopods. Living cephalopods include octopuses, cuttlefish, squid and nautiloids. Extinct cephalopods include ammonites.

The belemnite is the state fossil of Delaware, USA.

squid Belemnites were similar to squid (see left). But modern squid have arms with suckers and belemnite arms carried a series of small hooks for grabbing prey.

Belemnites have always fascinated people with their strange shapes, and they have many names throughout the world.

In England, they were called thunderbolts, and they were supposed to fall from the sky during thunderstorms. They were also called bullets, Devil's Fingers or Saint Peter's Fingers.

In Scotland, they were known as botstones or bat stones. They were used to cure horses.

In Chinese, belemnites are known as Jien-shih (sword stones).

In some areas of Scandinavian, they are called vateljus (gnomes' candles).

In Germany, they are known as Alpschoß (nightmare shot), Fingerstein (finger stone), Gespensterkerze (ghostly candle) and Katzenkegel (cat's skittle).



Timescale: Belemnites disappeared during the Cretaceous-Tertiary extinction event, when the dinosaurs and ammonites became extinct.
