3.2" Agatized Belemnite Fossil - Sweden
This is an "agatized" belemnite (Belemnitella mucronata) fossil from the Ignaberga lime quarry of Sweden.
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.
