RARE Fossil Ammonite PLATYPLEUREOCERAS BREVISPINA – Upper Pliensbachian, Jurassic: Radstock, UK – Alice Purnell Collection

£18.00

Presenting a RARE and scientifically significant fossil ammonite specimen: Platyp leureoceras brevispina, from the Upper Pliensbachian stage of the Early Jurassic, discovered at St Peter’s Field, Radstock, United Kingdom. This piece is part of the renowned Alice Purnell Collection, known for its exceptional curation and preservation.

Platyp leureoceras brevispina is a member of the family Dactylioceratidae, within the superfamily Eoderoceratoidea, and order Ammonitida. It is notable for its distinctively short, robust spines (hence “brevispina”), and dense ribbing. These features contribute to its aesthetic appeal and scientific value.

Geological & Scientific Details:

  • Scientific Name: Platyp leureoceras brevispina
  • Fossil Type: Ammonite (planispiral shell)
  • Geological Period: Jurassic
  • Stage: Upper Pliensbachian (~187–183 million years ago)
  • Zone: Margaritatus Zone (typical of this genus)
  • Location Found: St Peter’s Field, Radstock, Somerset, United Kingdom
  • Order: Ammonitida
  • Superfamily: Eoderoceratoidea
  • Family: Dactylioceratidae
  • Morphological Features: Thick ribs, distinctive short blunt spines on the outer whorl, evolute shell with visible inner whorls
  • Depositional Environment: Shallow marine epicontinental sea, with fine-grained sedimentation (likely mudstones and marls)

This ammonite is a key index fossil for the Pliensbachian and offers insights into cephalopod adaptation and evolution during the Early Jurassic. The shell’s spined ornamentation likely served defensive or hydrodynamic functions.

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

Please Note:

  • Scale Rule Squares / Cube = 1cm – full sizing is shown in the photo
  • The fossil pictured is the exact specimen you will receive
  • From the Alice Purnell Collection – chosen for its scientific interest and visual presentation

A unique fossil perfect for collectors, display, or academic reference.

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.
