Description
This listing features a polished and sliced British Belemnite fossil, expertly prepared to expose its beautiful internal structure. Sourced from Jurassic-aged deposits in the UK, this specimen provides a striking view of the internal anatomy of these extinct marine cephalopods.
You will receive the exact fossil shown in the photograph, with a 1cm cube scale included for accurate sizing—please refer to the photo for full measurements. This is a 100% genuine fossil specimen, professionally selected and sold with a Certificate of Authenticity.
Geological & Scientific Information:
- Type: Fossil Belemnite (internal rostrum of extinct squid-like cephalopod)
- Age: Jurassic (Approx. 201–145 million years old)
- Location Found: United Kingdom
- Order: Belemnitida
- Superfamily: Belemnopseina
- Family: Belemnitidae (typical for British Jurassic species)
- Morphological Features: This specimen has been polished and sliced to reveal the central phragmocone chamber system—an internal structure used for buoyancy. The growth rings and calcite crystallisation patterns are clearly visible, enhancing its aesthetic and educational value.
- Depositional Environment: Found in fine marine sedimentary layers formed in relatively calm, shallow shelf seas of the Jurassic period. These environments allowed for exceptional fossil preservation.
- Scientific Importance: Belemnites are important biostratigraphic markers and key indicators of marine ecosystem health and climate trends during the Mesozoic.
Additional Notes:
Belemnites were squid-like marine animals related to modern cuttlefish and squid. The internal hard parts (rostra) are commonly preserved as fossils, but specimens like this—sliced and polished to reveal internal features—are much rarer and ideal for both collectors and educators.
