This striking Tropidoceras ammonite fossil originates from the famous Upper Lias beds of Whitby, North Yorkshire, UK, dating to the Lower Jurassic period approximately 183 million years ago. This fossil is an exceptional example of this rare genus, showcasing beautiful preservation and classic coiling that is sought after by collectors and enthusiasts alike.

Tropidoceras is a genus of extinct ammonite belonging to the family Hildoceratidae within the superfamily Hildoceratoidea. It is characterised by strongly involute and compressed whorls, distinct ribbing, and often a pronounced keel. These features are finely preserved in this specimen.

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.
