Well-preserved, isolated belemnite.The name derives from the Greek "belemnon" = "projectile", which is why these fossils, which are often washed out of the earth after thunderstorms, are also known as thunderbolts.The dense, calcareous belemnite rostrum was the heaviest part of the internal skeleton. It acted as a counterweight to the rest of the body and helped the creature to maintain a more stable, horizontal position in the water. Because of this positioning, the animal was able to swim swiftly by expelling water from its siphon, similar to squids and octopuses today.Age: Cretaceous, Campanian (approx. 80 million years old);Locality: Höver near Hanover, Lower Saxony, GermanySize: approx. 6 cmColors on product photos may differ slightly from those of the original specimen due to technical reasons.The photos are for reference only.

Well-preserved, isolated belemnite.Belemnite derives its name from the Greek “belemnon” = “projectile”, which is why these fossils, frequently washed out of the earth after thunderstorms, are also known as thunderbolts. The thick, calcareous belemnite rostrum was the heaviest part of the inner skeleton. It acted as counterweight to the rest of the body and served to give these animals a more stable, horizontal position in water.Having this position allowed the cephalopods to swim swifter as well as more effortlessly by expelling water from their siphons, similar to modern squids and octopuses.Age: Cretaceous, Campanian (approx. 80 million years old);Locality: Höver near Hanover, Lower Saxony, GermanySize: approx. 9 cmColors on product photos may differ slightly from those of the original specimen due to technical reasons.The photos are for reference only.
