This beautifully preserved specimen displays the distinctive ribbed shell and coiled morphology characteristic of the Trimarginites genus, making it an exceptional addition to any fossil collection.

Geology & Fossil Type:

This ammonite originates from the Middle Oxfordian, a stage within the Upper Jurassic, dating back approximately 160 million years. The Oxfordian period was marked by warm, shallow seas, which provided an ideal environment for ammonites to thrive. Fossils from this period are crucial for biostratigraphic dating, allowing geologists to correlate rock layers worldwide.

Trimarginites trimarginites belonged to the subclass Ammonoidea, an extinct group of marine mollusks closely related to modern squids and octopuses. These ammonites had intricately ribbed shells that provided structural support and protection from predators. Their chambered shells allowed for buoyancy control, enabling them to move efficiently through prehistoric oceans.

  • 100% Genuine Fossil – No Replicas or Synthetics
  • Comes with a Certificate of Authenticity
  • From the Alice Purnell Collection, a highly regarded fossil collection
  • Scale cube = 1cm for size reference (please see photos for full dimensions)

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.
