£9.00

Authentic Lamberticeras lamberti Fossil Ammonite from France

This is a genuine Lamberticeras lamberti ammonite fossil from the Upper Callovian Stage of the Jurassic Period, dating to approximately 164–163 million years ago. Collected in Villeurs, France, this specimen is a striking and scientifically significant ammonite belonging to the Perisphinctidae family. Known for its beautifully ribbed shell and importance as an index fossil, Lamberticeras lamberti is a prized piece for collectors and researchers alike. The fossil pictured is the exact specimen you will receive, and it is accompanied by a Certificate of Authenticity, ensuring both provenance and quality.

Geological Context and Age

The Callovian Stage is part of the Middle Jurassic and represents a time of thriving marine ecosystems across Europe. The Upper Callovian in particular is associated with widespread shallow seas, rich in ammonites, bivalves, and marine reptiles. Lamberticeras lamberti is one of the most distinctive ammonites of this interval, and its presence is used by paleontologists to identify the Lamberti Zone, a globally recognised biozone within the Upper Callovian. This makes the species both scientifically and stratigraphically important, providing a precise tool for dating Jurassic marine rocks.

Scientific Classification

  • Species: Lamberticeras lamberti
  • Genus: Lamberticeras
  • Family: Perisphinctidae
  • Superfamily: Perisphinctoidea
  • Order: Ammonitida
  • Class: Cephalopoda
  • Age: Upper Callovian, Jurassic (~164–163 million years ago)
  • Locality: Villeurs, France

Morphological Features

The shell of Lamberticeras lamberti is characterised by strong ribbing that radiates across the flanks and extends to the venter, producing a bold and sculptured appearance. The whorls are compressed yet robust, giving the ammonite a distinctive form that sets it apart from other Callovian species. These ribs may bifurcate or remain simple, depending on growth stage, making each specimen unique in its details. This species is not only aesthetically striking but also highly informative, as its morphology is a classic example of Callovian ammonite development.

Stratigraphic and Paleontological Significance

Lamberticeras lamberti is one of the most important index fossils of the Jurassic, defining the Lamberti Biozone within the Upper Callovian. This biozone is recognised internationally and allows geologists to correlate rock layers across different regions with remarkable accuracy. Its widespread distribution in European Jurassic strata highlights its ecological success during this period and cements its importance in paleontological research.

Depositional Environment

The deposits of Villeurs, France, where this specimen was found, represent shallow marine shelf environments dominated by fine-grained sediments such as marls and limestones. These conditions allowed for exceptional preservation, capturing fine ribbing and intricate shell details. Ammonites like Lamberticeras lamberti thrived in these nutrient-rich seas as active predators, likely preying on smaller molluscs, crustaceans, and other marine organisms.

Collector’s Appeal and Educational Value

This specimen is an ideal addition to any fossil collection. For collectors, its scientific importance and visual appeal make it a standout piece. For educators and students, it provides an excellent teaching example of ammonite evolution, morphology, and stratigraphic use. Its role as a marker fossil for the Lamberti Zone also underscores its significance in geology and paleontology.

Item Details

  • Type: Fossil Ammonite – Lamberticeras lamberti
  • Geological Age: Upper Callovian, Jurassic (~164–163 million years ago)
  • Origin: Villeurs, France
  • Notable Features: Distinct ribbing, classic Callovian ammonite morphology
  • Scale: Rule squares/cube = 1 cm (see photos for accurate sizing)
  • Authenticity: 100% genuine fossil with Certificate of Authenticity

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.
