RARE FOSSIL AMMONITE – Quenstedtoceras lamberti

Upper Callovian Stage | Middle–Late Jurassic (~161–163 million years ago)

Origin: Switzerland

From the Renowned Alice Purnell Collection

Includes Certificate of Authenticity

This listing offers an exceptional example of the rare fossil ammonite species Quenstedtoceras lamberti, preserved from the Upper Callovian Stage of the Jurassic Period, collected in Switzerland. Ammonites from this genus are highly significant for Callovian biostratigraphy and are especially prized due to their distinctive ribbed morphology and tight coiling.

The specimen has been carefully selected, and the photos show the exact fossil you will receive. A scale cube (1cm) is included in the images for size reference. For full dimensions, please see the accompanying photo.

GEOLOGICAL & TAXONOMIC DETAILS:

  • Species: Quenstedtoceras lamberti
  • Family: Kosmoceratidae
  • Superfamily: Stephanoceratoidea
  • Order: Ammonitida
  • Class: Cephalopoda
  • Phylum: Mollusca
  • Geological Stage: Upper Callovian (Late Middle Jurassic)
  • Biozone: lamberti Zone (Named after this species; serves as the index fossil for the uppermost Callovian biozone in Europe)
  • Depositional Environment: Shallow epicontinental seas with moderate to low energy, rich in pelagic and benthic fauna
  • Formation (likely): Swiss marine Callovian strata – part of the pre-Alpine sedimentary basin system

MORPHOLOGY & FEATURES:

  • Shell Form: Moderately involute with relatively compressed whorls
  • Ribbing: Strong, dense, bifurcating ribs that cross the venter without interruption, characteristic of the genus
  • Whorl Section: Slightly oval to subquadrate, with a steep umbilical wall
  • Size: Medium-sized adult ammonite species
  • Notable Use: Q. lamberti is a critical biostratigraphic marker in European Jurassic sedimentology and commonly used in correlation between regions
  • Scientific Significance: A key index fossil, especially in western European Callovian stratigraphy

COLLECTOR & DISPLAY VALUE:

This specimen hails from the Alice Purnell Collection, a name known for high-quality, expertly identified palaeontological material. Its rare preservation and precise taxonomic identification offer scientific and display value, perfect for collectors, educators, or researchers.

The fossil is 100% genuine, and a Certificate of Authenticity is provided.

SPECIMEN DETAILS:

  • Species: Quenstedtoceras lamberti
  • Age: Upper Callovian (~161–163 million years old)
  • Location: Switzerland
  • Provenance: Alice Purnell Collection
  • Preservation: Excellent ribbing and morphological integrity
  • Scale Reference: 1cm cube visible in images
  • Authenticity: Certificate included

A scientifically significant and visually striking ammonite that marks a critical point in Jurassic evolution and stratigraphy — ideal for fossil enthusiasts and collectors of rare European ammonites.

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.
