£48.00

This listing is for a Rare 4.5″ Fossil Ammonite (Lioceras bradfordensis) from the Aalenian Stage of the Middle Jurassic (Inferior Oolite Formation), discovered at Horn Park Quarry, Dorset, United Kingdom.

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: Lioceras bradfordensis.
  • Order: Ammonitida.
  • Superfamily: Hammatoceratoidea.
  • Family: Graphoceratidae.
  • Geological Period: Jurassic.
  • Stage/Age: Aalenian (approx. 174 – 170 million years ago).
  • Formation: Inferior Oolite.
  • Locality: Horn Park, Dorset, UK.

 

Notable Features & Morphology:

  • Shell Form: Moderately involute with compressed whorls.
  • Ribs: Distinct ribbing crossing the flanks, often slightly sinuous.
  • Whorl Section: Narrow, with sharp ribbing giving the fossil a striking appearance.
  • Size: A well-preserved 4.5″ specimen, considered large for this species.

 

Depositional Environment:

The Inferior Oolite of Dorset was deposited in a shallow, warm marine environment rich in calcium carbonate. This setting was ideal for the preservation of ammonites, brachiopods, and marine fauna in oolitic limestone beds.

 

Scientific & Collecting Importance:

Lioceras bradfordensis is an important biozone ammonite, aiding in the correlation of Aalenian age rocks across Europe. Its distinctive ribbing and preservation within the Inferior Oolite make it highly desirable among collectors and scientifically valuable for Jurassic stratigraphy.

 

Why Buy This Fossil?

  • A rare and fine ammonite from the renowned Horn Park site in Dorset.
  • Excellent preservation with well-defined ribbing.
  • A highly desirable specimen for collectors of ammonites, Inferior Oolite fossils, or UK Jurassic 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.
