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.
