Oxynoticeras Pyrite Fossil Ammonite – Disc Shape – Jurassic UK – Upper Sinemurian – Bishops Cleeve – With COA

Original price was: £10.80.Current price is: £9.72.

Available here is a visually striking Oxynoticeras fossil ammonite preserved in gleaming pyrite, originating from the Upper Sinemurian stage of the Jurassic Period, and collected from Bishops Cleeve, Gloucestershire, United Kingdom. This highly sought-after ammonite is known for its clean, flat, disc-like morphology and metallic sheen resulting from natural pyritisation.

Oxynoticeras belongs to:

  • Order: Ammonitida
  • Superfamily: Psiloceratoidea
  • Family: Oxynoticeratidae
  • Genus: Oxynoticeras
  • Geological Stage: Upper Sinemurian (approx. 190 million years ago)
  • Formation: Blue Lias Formation (Bishops Cleeve exposure)
  • Depositional Environment: Shallow marine shelf, low-energy anoxic basin promoting exceptional pyrite preservation
  • Biozone: Likely Oxynoticeras oxynotum Zone or Arietites bucklandi Zone depending on precise stratigraphy

The genus is notable for:

  • Highly compressed, discoidal shell
  • Very fine ribbing or near-smooth flanks
  • Sharp, angular venters
  • Frequent pyrite replacement, giving a golden-bronze metallic appearance

This ammonite represents a textbook example of early Jurassic ammonite morphology and is often used in biostratigraphy and display collections. Its shimmering metallic coating and aesthetic disc form make it a favourite for collectors.

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.
