Three Jurassic Belemnite (Passaloteuthis) Fossils - Germany

Here are three fossil belemnites (Passaloteuthis sp.) from the Jurassic age, Posidonia Shale of Holzmaden, Germany. These belemnites were prepped free of the shale they were found in, and are mounted to this section of shale that comes from the same locale. One belemnite measures 2.8" long while the others are 2.7" and 2.4" long. There are a couple minor repaired cracks through each belemnite. The belemnites have the distinctive, metallic sheen of pyritized fossils.

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 ten arms but, unlike modern squid, these arms had small hooks instead of suckers.
