Rare Geyerina fasciata Fossil Ammonite | Lower Bajocian Jurassic | Burton Bradstock UK | Genuine Specimen with COA

£60.00

This listing is for a Rare Fossil Ammonite (Geyerina fasciata) from the Lower Bajocian Stage of the Middle Jurassic, discovered at Burton Bradstock, 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: Geyerina fasciata.
  • Order: Ammonitida.
  • Superfamily: Stephanoceratoidea.
  • Family: Stephanoceratidae.
  • Geological Period: Jurassic.
  • Stage/Age: Lower Bajocian (approx. 170 – 168 million years ago).
  • Locality: Burton Bradstock, Dorset, UK.

 

Notable Features & Morphology:

  • Shell Form: Moderately involute with compressed to sub-rounded whorls.
  • Ribs: Strong, regular ribbing crossing the flanks, often bifurcating, typical of Geyerina.
  • Whorl Section: Slightly compressed, giving the ammonite a striking appearance.
  • Size: A rare, well-preserved specimen, highly desirable for collectors.

 

Depositional Environment:

During the Bajocian, the Burton Bradstock area was part of a shallow marine environment with carbonate-rich sediments. These conditions provided excellent preservation of ammonites, brachiopods, and other marine fauna within limestone and marl beds.

 

Scientific & Collecting Importance:

Geyerina fasciata is an important ammonite species for biostratigraphic correlation in the Bajocian. Its distinct ribbing and shell form make it valuable for identifying and dating Jurassic deposits, while also being prized among fossil collectors.

 

Why Buy This Fossil?

  • A rare ammonite species from Burton Bradstock, Dorset.
  • Excellent preservation with diagnostic ribbing.
  • An ideal specimen for collectors of Jurassic ammonites or UK fossil 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.
