Rare Reynesella sowerbyi Fossil Ammonite | Middle Bajocian Jurassic | Switzerland | Genuine Specimen with COA

£60.00

This listing is for a Rare Fossil Ammonite (Reynesella sowerbyi) from the Middle Bajocian Stage of the Middle Jurassic, discovered in Switzerland.

100% Genuine Fossil Specimen – All of our fossils are authentic and come with a Certificate of Authenticity.

Exact Specimen Shown – The photos provided are of the actual fossil you will receive.

Scale for Reference – Scale rule squares/cube = 1cm. Please see photos for full sizing.

 

Geological & Scientific Details:

  • Fossil Type: Ammonite (extinct marine mollusc, related to squid and octopus).
  • Species: Reynesella sowerbyi.
  • Order: Ammonitida.
  • Superfamily: Stephanoceratoidea.
  • Family: Stephanoceratidae.
  • Geological Period: Jurassic.
  • Stage/Age: Middle Bajocian (approx. 170 – 168 million years ago).
  • Locality: Switzerland.

 

Notable Features & Morphology:

  • Shell Form: Involute with robust ornamentation.
  • Ribs: Strong, bifurcating ribs across the flanks, curving toward the venter – a diagnostic feature of Reynesella.
  • Whorl Section: Sub-rounded with well-defined ribbing, making this ammonite visually striking.
  • Size: A rare, well-preserved specimen, highly desirable for collectors.

 

Depositional Environment:

During the Bajocian, Switzerland was part of a shallow epicontinental sea environment where carbonate sedimentation dominated. These seas provided ideal conditions for ammonite preservation, with fine-grained limestones and marls capturing exquisite fossil detail.

 

Scientific & Collecting Importance:

Reynesella sowerbyi is a significant ammonite for biostratigraphic studies in the Bajocian. Its distinctive ribbing and shell morphology make it an important index fossil, aiding correlation of Middle Jurassic strata across Europe.

 

Why Buy This Fossil?

  • A rare ammonite species from the Middle Bajocian of Switzerland.
  • Excellent preservation with bold ribbing and diagnostic morphology.
  • A valuable specimen for collectors of Jurassic ammonites or European fossil material.
  • Supplied with a Certificate of Authenticity guaranteeing its provenance.

 

All of our fossils are responsibly sourced, carefully prepared, and chosen for quality.

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.
