This listing showcases a rare 3-inch fossil ammonite, Eoderoceras bispinigerum, originating from the Lower Pliensbachian Stage of the Early Jurassic Period. This specimen was collected from the classic fossil site of Radstock Grove Quarry, Radstock, Somerset, United Kingdom.

The fossil shown in the photo is the exact specimen you will receive. Each square in the scale image represents 1cm — see image for full sizing and scale.

This ammonite is a superb collector’s item and a significant addition to any fossil, palaeontology, or geology collection.

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

Geological & Scientific Information:

  • Fossil Type: Ammonite
  • Species: Eoderoceras bispinigerum
  • Order: Ammonitida
  • Superfamily: Eoderoceratoidea
  • Family: Eoderoceratidae
  • Geological Stage: Lower Pliensbachian (approx. 190.8 – 182.7 million years ago)
  • Biozone: Ibex–Davoei zones (frequently associated with the Davoei Subzone)
  • Formation: Lower Lias Formation
  • Locality: Radstock Grove Quarry, Somerset, England, UK
  • Depositional Environment: Offshore marine shelf, deposited in low-energy anoxic to dysoxic conditions typical of the Early Jurassic Wessex Basin

Morphology & Notable Features:

  • Strongly ribbed, evolute shell with widely exposed umbilicus
  • Notable for its tuberculate ornamentation: spines or tubercles typically present on the flanks or umbilical shoulders
  • Prominent bifurcating ribs give it a striking appearance
  • Excellent preservation of ribbing and whorl structure
  • A key morphological link between ancestral Jurassic ammonites and more derived forms

Scientific Significance:

Eoderoceras bispinigerum is biostratigraphically important and represents one of the earliest, highly ornamented ammonite lineages of the Pliensbachian. It is notable for its transitional morphology between earlier Hettangian forms and more derived Eoderoceratids.

The species is often used as an indicator fossil in correlating Lower Jurassic marine sequences, particularly within the UK. Its characteristic spines and ribbing make it one of the more visually distinct ammonites of its age.

Originally described by S.S. Buckman in the early 20th century, it has long been a staple of Jurassic ammonite research and curation.

Ideal For:

  • Serious fossil and ammonite collectors
  • Biostratigraphic or palaeontological study collections
  • Natural history display
  • Educational use in geology or Earth science

What You Will Receive:

  • The exact specimen of Eoderoceras bispinigerum as shown
  • Certificate of Authenticity
  • Safe, secure packaging for peace of mind during delivery

Feel free to reach out if you have any questions. We are always happy to help with further information or support your fossil collecting journey.

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.
