RARE Fossil Ammonite – Siemiradzkia aurigera

Geological Period: Jurassic

Stage: Lower Oxfordian (~163–161 million years ago)

Location: Nevers, Nièvre, Burgundy (Bourgogne), France

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity

This listing features a rare and scientifically notable specimen of the ammonite species Siemiradzkia aurigera, originating from the Lower Oxfordian stage of the Jurassic Period. It was found in the well-known fossiliferous deposits near Nevers, France – an area famed for its Oxfordian marine sedimentary rocks and diverse ammonite fauna.

About the Species:

  • Genus: Siemiradzkia
  • Species: aurigera
  • Family: Perisphinctidae
  • Superfamily: Perisphinctoidea
  • Order: Ammonitida
  • Formally Described by: Quenstedt (species name authority)

This genus is known for its ornate shell morphology, typically featuring evolute coiling, moderately compressed whorls, and bifurcating ribs that extend cleanly across the venter. The ornamentation and suture patterns in Siemiradzkia aurigera help differentiate it from closely related perisphinctid ammonites of similar age.

Geological and Palaeoenvironmental Information:

  • Geological Stage: Lower Oxfordian
  • Depositional Environment: Shallow epicontinental marine shelf, characterised by carbonate platform sedimentation (limestones and marls).
  • Biostratigraphy/Biozone: Often associated with Gregoryceras transversarium and Perisphinctes plicatilis zones in the lower Oxfordian ammonite zonation scheme.
  • Notable Features: High-quality preservation, ribbed ornamentation, and moderate involution – ideal for both aesthetic and scientific interest.

Specimen Details:

This is the exact fossil specimen you will receive – professionally photographed and carefully selected for display and educational value. The specimen is well-preserved, showcasing key taxonomic features with excellent contrast against the matrix.

Size & Scale:

Scale cube/rule = 1cm. Full sizing available in listing photos.

Whether you’re a dedicated collector, educator, or palaeontology enthusiast, this is a standout example of Siemiradzkia aurigera from a classic Oxfordian locality. An ideal addition to any Jurassic ammonite or European fossil collection.

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.
