Sliced British Jurassic Ammonite Fossil Polished Half Jurassic Dorset UK Genuine Display

£36.00

This stunning sliced and polished ammonite fossil is a genuine specimen from the Jurassic coast of Dorset, UK. Carefully cut and polished to reveal the beautiful internal chamber structure, this display piece showcases the intricate natural patterns and mineral infill that characterise fossilised ammonites.

Ammonites are extinct marine molluscs from the subclass Ammonoidea, belonging to the class Cephalopoda, closely related to modern squids and octopuses. Their spiral shells were divided into chambers, with the animal inhabiting the outermost one. These fossils are among the most iconic of the Mesozoic era, particularly abundant in Jurassic marine strata.

This particular specimen originates from the fossil-rich Jurassic deposits of Dorset, a UNESCO World Heritage Site renowned for its geological significance. The sliced and polished face reveals the septa (chamber walls), often highlighted by mineralisation including calcite and aragonite, creating a visually striking cross-section.

The photograph shows the actual specimen you will receive. Scale rule squares/cube = 1cm. This ammonite has been selected for its quality and aesthetic appeal, making it an ideal collector’s item or display piece.

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.
