Genuine Quenstedtoceras lamberti Fossil Ammonite

This listing offers a superb specimen of Quenstedtoceras lamberti, a fossil ammonite from the Oxfordian Stage of the Jurassic Period, discovered at Tidmoor Point, The Fleet, Dorset, United Kingdom. Dating back around 163–157 million years, this ammonite represents a fascinating chapter in Earth’s prehistoric marine life. The exact specimen photographed is the one you will receive, and it comes with a Certificate of Authenticity, ensuring its provenance and value as a true geological treasure.

Geological Background

The Oxfordian Stage marks the beginning of the Upper Jurassic, a period characterised by significant marine transgressions and the flourishing of ammonite faunas across Europe. The deposits at Tidmoor Point, The Fleet in Dorset, form part of the renowned Jurassic Coast, a UNESCO World Heritage Site celebrated for its rich and continuous fossil record. This area preserves exceptional examples of marine life that thrived in the shallow seas of the Jurassic.

During this time, extensive epicontinental seas covered large portions of Europe. The fine-grained sediments deposited in these environments provided excellent preservation conditions for ammonites, which today serve as essential biostratigraphic markers for correlating Jurassic strata across different regions.

Scientific Classification

  • Species: Quenstedtoceras lamberti
  • Genus: Quenstedtoceras
  • Family: Cardioceratidae
  • Superfamily: Stephanoceratoidea
  • Order: Ammonitida
  • Class: Cephalopoda
  • Geological Stage: Oxfordian, Jurassic (~163–157 million years ago)
  • Locality: Tidmoor Point, The Fleet, Dorset, United Kingdom

Morphological Features

Quenstedtoceras lamberti is a highly recognisable ammonite, characterised by its distinctive ribbing pattern and compressed whorls. The ribs are strong, regularly spaced, and often bifurcate across the shell, giving it a striking and symmetrical appearance. The suture lines are complex, as is typical of Jurassic ammonites, adding further beauty to the fossil.

As a free-swimming cephalopod, this ammonite was an active predator in the Jurassic seas, using its tentacles to capture prey while its coiled shell provided buoyancy control and protection. Fossils such as this reveal both the ecological role of ammonites and their evolutionary importance within marine ecosystems.

Stratigraphic and Scientific Significance

Quenstedtoceras lamberti is a particularly significant ammonite in Jurassic stratigraphy. It serves as the index fossil for the Lamberti Zone, a critical biozone within the Oxfordian Stage. This makes the species not only attractive to collectors but also vital to geologists for precise correlation of Jurassic rock sequences. The presence of this ammonite provides clear evidence for the age and environment of the sediments in which it is found.

Specimens from Dorset, especially from the Jurassic Coast, carry additional scientific value due to the global importance of the region in defining Jurassic stratigraphy. The site has provided fossil evidence that has shaped our understanding of Earth’s history for over two centuries.

Depositional Environment

The environment in which Quenstedtoceras lamberti lived was a shallow marine seaway with stable conditions conducive to ammonite proliferation. Fine sediments buried their shells after death, leading to the superb preservation seen in specimens such as this. The Dorset deposits are renowned for producing ammonites with well-preserved ribbing and whorl structures, showcasing the unique morphology of the species.

Collector and Display Value

This Quenstedtoceras lamberti ammonite is a classic specimen for collectors, combining both scientific importance and natural beauty. Its diagnostic ribbing and historical role as an index fossil for the Oxfordian Lamberti Zone make it a centrepiece for any fossil collection. Whether for research, education, or display, this ammonite provides a tangible link to the rich marine ecosystems of the Jurassic Coast.

  • Type: Fossil Ammonite – Quenstedtoceras lamberti
  • Age: Oxfordian, Jurassic (~163–157 million years ago)
  • Location: Tidmoor Point, The Fleet, Dorset, United Kingdom
  • Scale: Rule squares/cube = 1 cm (see photographs for precise sizing)
  • Authenticity: 100% genuine specimen with Certificate of Authenticity
  • Guarantee: The fossil shown in the photographs is the exact one you will receive

This specimen represents an extraordinary opportunity to own a scientifically significant ammonite fossil from one of the world’s most famous Jurassic localities.

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.
