Rare Fossil Goliathiceras ammonoides Ammonite, Oxfordian, Jurassic, Oxfordshire, United Kingdom

£36.00

This listing is for a rare and genuine fossil ammonite specimen: Goliathiceras ammonoides, originating from the Oxfordian Stage of the Late Jurassic Period, discovered in Oxfordshire, United Kingdom.

This exceptional ammonite is part of the Perisphinctidae family, within the superfamily Perisphinctoidea and the order Ammonitida. The genus Goliathiceras is notable for its large, robust shells and finely ribbed morphology, often displaying impressive whorls and pronounced growth lines.

This species, Goliathiceras ammonoides, is known for its:

  • Large size potential, hinting at its name “Goliathiceras”
  • Thick shell and rounded whorls
  • Moderately strong ribbing, with a somewhat evolute coiling
  • Preservation in marine sedimentary limestone typical of the Oxfordian deposits of southern England

Geological Context:

  • Fossil Type: Ammonite
  • Species: Goliathiceras ammonoides
  • Order: Ammonitida
  • Superfamily: Perisphinctoidea
  • Family: Perisphinctidae
  • Geological Stage: Oxfordian
  • Period: Jurassic (approx. 163.5 to 157.3 million years ago)
  • Locality: Oxfordshire, UK
  • Depositional Environment: Marine shelf environment with clayey-limestone sedimentation

This fossil represents part of the rich ammonite diversity that flourished in European epicontinental seas during the Jurassic. The Goliathiceras genus was likely a fast-moving nektonic carnivore, using jet propulsion to navigate the shallow seas.

Specimen Information:

  • The fossil is presented as photographed: you will receive the exact item shown
  • Size reference: Scale rule / cube in photos is in centimetres (1cm squares)
  • Comes with our Certificate of Authenticity, confirming it as a genuine fossil specimen

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

Perfect for collectors, educators, museums, or anyone with an interest in the ancient past. This Goliathiceras ammonoides fossil is a rare and scientifically valuable example of Upper Jurassic marine life from the UK.

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.
