Porpoceras beurlini Fossil Ammonite from Aveyron, France

This listing offers a Porpoceras beurlini fossil ammonite, a rare and scientifically valuable specimen from the Lower Toarcian stage of the Jurassic period. Formerly classified under the genus Peronoceras, this species is now placed in Porpoceras and represents an important ammonite type from the rich Jurassic deposits of southern France. The fossil shown in the photographs is the exact specimen you will receive, with a 1 cm scale cube included for accurate size reference. Every specimen is 100% genuine and will be supplied with a Certificate of Authenticity.

Geological Age and Setting – Lower Toarcian, Jurassic

This ammonite comes from the Lower Toarcian stage of the Early Jurassic, approximately 182–174 million years ago. The region of Aveyron, France, formed part of the vast Tethys Ocean margin, where shallow seas supported diverse ecosystems and produced sedimentary rocks rich in ammonites, belemnites, bivalves, and other marine life.

The Toarcian is a key stage in Jurassic history, known for the Toarcian Oceanic Anoxic Event (T-OAE), a period of significant climatic and oceanographic change that shaped the evolution and distribution of marine organisms. Fossils like Porpoceras beurlini are essential for understanding the biodiversity of this era.

Species and Classification

  • Genus: Porpoceras (formerly Peronoceras)
  • Species: beurlini
  • Order: Ammonitida
  • Superfamily: Hildoceratoidea
  • Family: Hildoceratidae

As a member of the Hildoceratidae, Porpoceras beurlini is characterised by its ribbed shell structure and importance in ammonite biozonation. These ammonites are often used as index fossils, helping palaeontologists to date and correlate Toarcian deposits across Europe.

Morphological Features

The Porpoceras beurlini ammonite is distinct for its bold and attractive shell morphology:

  • Shell form: Evolute coiling, with inner whorls exposed.
  • Ribbing: Strong, prominent ribs running across the flanks, often ending in subtle tubercles.
  • Whorl profile: Rounded and robust, giving the ammonite a powerful and easily recognisable form.
  • Ornamentation: Ribbing and occasional nodal features enhance both its taxonomic significance and display value.
  • Sutures: Complex suture patterns, typical of the Hildoceratidae, adding fine detail to the fossil.

These traits make the species visually striking and scientifically important, serving both as an educational specimen and a collector’s piece.

Stratigraphy and Biozone Importance

Porpoceras beurlini is a valuable ammonite for defining Lower Toarcian biozones, contributing to high-resolution stratigraphy across Tethyan Europe. Its presence in the Aveyron deposits helps geologists refine the dating of Jurassic sequences and improves understanding of faunal distribution during the Toarcian stage.

Collector and Scientific Value

  • Collectors will prize this specimen for its rarity, strong ribbing, and provenance from Aveyron, a classic French fossil locality.
  • Researchers and educators value it as a key ammonite for Toarcian biostratigraphy and palaeogeography.
  • For display, its bold ribbing and robust structure make it a visually appealing specimen, ideal as a centrepiece in a collection of natural history.

Authenticity and Guarantee

All of our fossils are responsibly sourced and are 100% genuine specimens. This Porpoceras beurlini ammonite has been carefully chosen for its quality, preservation, and scientific importance. Every purchase includes a Certificate of Authenticity, ensuring confidence in its provenance and authenticity.
