4.8" Fossil Belemnite (Acrocoelites) - Mistelgau, Germany

This is a 4.8" fossil Belemnite of the genus Acrocoelites, collected from the Jurensismergel Formation of Mistelgau, Germany. This is the fossilized "cone" portion of the belemnite.

There is a repaired crack through this specimen.

Belemnites are probably the most well known extinct cephalopod after the ammonites. They lived during the Jurassic and Cretaceous periods and are fairly common fossils found throughout the world. They had a hard, internal, cone shaped structure that is often preserved as a fossil though it is not technically a shell. They had 10 arms but unlike modern squid these arms had small hooks instead of suckers.
