£144.00

A superb and rare 6.5-inch fossil ammonite: Quenstedtoceras lamberti from the Upper Callovian Stage of the Jurassic Period, discovered in the classic Jurassic marine beds of Gristhorpe, Yorkshire, United Kingdom. This finely preserved specimen offers a beautifully detailed example of one of the most iconic ammonites of the Oxford Clay and Callovian seas.

Geological & Palaeontological Information:

  • Fossil Type: Ammonite
  • Species: Quenstedtoceras lamberti (named by Oppel, 1857)
  • Geological Period: Jurassic
  • Stage: Upper Callovian (~161 to 158 million years ago)
  • Location: Gristhorpe, Yorkshire, England, UK
  • Depositional Environment: Offshore marine mudstone environment, part of the Oxford Clay and Kellaways Formation
  • Order: Ammonitida
  • Superfamily: Stephanoceratoidea
  • Family: Cardioceratidae
  • Biozone: lamberti Zone — a key ammonite biozone defining the uppermost Callovian interval

 

Morphological Features:

  • Involute shell with tightly coiled whorls
  • Finely ribbed with sharp, dense ornamentation across flanks
  • Rounded venter with strong ribbing extending continuously from umbilicus to keel
  • Precise symmetry and strong curvature characteristic of Quenstedtoceras

 

Notable Points:

  • Quenstedtoceras lamberti defines the uppermost ammonite biozone of the Callovian, used globally in Jurassic stratigraphy
  • Fossils from Gristhorpe are becoming increasingly rare due to erosion and accessibility limitations
  • Excellent preservation and large size make this a collector-grade or museum-quality specimen

 

Why This Fossil Stands Out:

  • Rare and stratigraphically significant species
  • Beautiful ribbing and form ideal for display or research
  • Supplied with a Certificate of Authenticity
  • 100% genuine and ethically sourced fossil
  • Suitable for collectors, educators, palaeontology enthusiasts, or natural history displays

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.
