Sliced & polished limestone ammonite fossil – jurassic marine cephalopod – somerset, uk – 100% genuine with certificate

Description

This listing features a genuine sliced and polished ammonite fossil, sourced from Jurassic limestone deposits in Somerset, UK. These ammonites date back approximately 190 to 170 million years, when they lived in warm, shallow seas that covered much of what is now southern England.

Ammonites are one of the most recognisable fossils in the world, thanks to their distinctive spiral shells. Though often mistaken for snail shells, ammonites were actually marine cephalopods, more closely related to squid, octopuses, and cuttlefish than to gastropods. They used their chambered shells for buoyancy control, moving efficiently through the oceans by regulating gases within the shell’s internal chambers.

This particular specimen has been expertly sliced and polished to expose its inner chambers, revealing intricate crystalised structures and natural mineralisation patterns. The fossil showcases the beauty of ancient marine life while offering insight into the biology and evolution of these now-extinct creatures.

Geological Context: This ammonite was collected from Jurassic limestone beds in Somerset, a region well-known for its abundance of marine fossils, especially from the Lower and Middle Jurassic periods. These layers represent sediment laid down in ancient seabeds, perfectly preserving ammonites and other marine organisms over millions of years.
