Description
This listing features an authentic and scientifically significant fossil ammonite of the species Bigotites petri from the Middle Callovian stage of the Jurassic period, dated to approximately 165–163 million years ago. This beautiful fossil was found in Normandy, France, and is part of the reputable Alice Purnell Collection, known for its expertly preserved and catalogued fossil specimens.
Bigotites petri belongs to the family Perisphinctidae and is characterised by its finely ribbed, moderately evolute shell with defined spiral structure. These ammonites were fast-swimming, nektonic cephalopods that thrived in marine environments during the Middle Jurassic. Their coiled, chambered shells helped control buoyancy, allowing them to pursue prey and evade predators in warm shallow seas.
This particular specimen exhibits clear detail in the shell ribs and coiling, making it an excellent candidate for both scientific appreciation and display.
Geological Context: The Middle Callovian Stage of the Jurassic period is known for widespread marine transgressions that created ideal environments for the flourishing of ammonite species. The Normandy region of France is renowned for its well-exposed marine sedimentary formations, which produce a wide range of ammonites used extensively in stratigraphy and palaeontology.
