£60.00

A stunning and RARE specimen of the ammonite Bigotites thevenui, from the Upper Bajocian stage of the Jurassic period, discovered in the renowned fossil beds of Calvados, Normandy, France. This specimen exemplifies the detailed ornamentation and whorl structure characteristic of this uncommon genus.

The fossil you see in the photo is the exact piece you will receive, with a 1cm scale cube included for precise size reference. This is a 100% genuine fossil, professionally selected and supplied with a Certificate of Authenticity.

Geological & Scientific Information:

  • Species: Bigotites thevenui
  • Type: Fossil Ammonite (extinct marine cephalopod)
  • Age: Approx. 170–168 million years old
  • Geological Period: Jurassic
  • Stage: Upper Bajocian (Middle Jurassic)
  • Location Found: Calvados, Normandy, France
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Stephanoceratidae
  • Morphological Features: Bigotites is recognised by its evolute shell, with wide umbilicus, strongly ribbed whorls, and periodic tuberculation. Bifurcating ribs radiate prominently across the flanks, and the shell has a planispiral coiling typical of Stephanoceratoidea.
  • Depositional Environment: Shallow marine shelf with calcareous and silty mud deposits—an environment ideal for fossil preservation. Normandy’s Upper Bajocian layers are well known for their exceptional ammonite faunas.
  • Scientific Importance: Bigotites thevenui is a useful index fossil for refining ammonite biostratigraphy in the Middle Jurassic of northern France. The genus is relatively rare, making specimens highly collectable.

Additional Notes:

Ammonites like this one not only showcase nature’s symmetry and form but also provide vital clues about ancient ocean conditions and faunal evolution. This specimen is especially valuable due to its preservation quality and distinct morphological features.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
