3.2" Belemnite Fossil In Rock - Jedrzejow, Poland
This is a 3.2" long, fossil belemnite (Belemitella murconata) from Jedrzejow, Poland. It is still partially embedded in the rock it was found in creating a nice display.
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.
