RARE PLATYPLEUROCERAS Ammonite Fossil Upper Lias Jurassic Whitby Yorkshire UK Genuine Specimen

£12.60

This rare Platypuleuroceras ammonite fossil was discovered in the world-renowned fossil locality of Whitby, North Yorkshire, UK. Dating from the Upper Lias (Lower Jurassic), approximately 183 to 174 million years ago, this fossil represents a well-preserved example of the extinct marine cephalopods that thrived in the ancient Jurassic seas.

Platypuleuroceras is known for its involute shell structure with a compressed, disc-shaped form and relatively smooth flanks, sometimes exhibiting fine ribbing. These ammonites are members of the Hildoceratidae family, a group notable for their elegant and varied shell morphology and ecological significance during the Early Jurassic.

This particular specimen comes from the Whitby Mudstone Formation, which is famous for preserving high-quality marine fossils. The depositional environment was a deep marine basin with anoxic bottom conditions, aiding exceptional fossil preservation.

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.
