This is a Dactylioceras fossil ammonite, dating back to the Lower Toarcian stage of the Early Jurassic period (~183-180 million years ago), discovered in Whitby, United Kingdom. Dactylioceras is one of the most well-known genera of Jurassic ammonites, easily recognized by its evolute shell with fine, closely spaced ribs and a pronounced keel.

Ammonites from Whitby’s famous Lower Jurassic deposits are highly sought after due to their exceptional preservation in the Whitby Mudstone Formation, a region known for producing world-class fossils.

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.
