5″ Lytoceras Fossil Ammonite – Jurassic Ilminster Somerset UK – Beacon Limestone – Certified Specimen

Original price was: £42.00.Current price is: £37.80.

A beautifully preserved 5″ Lytoceras ammonite fossil from the renowned Beacon Limestone Formation, found at Ilminster, Somerset, UK. This classic Jurassic ammonite displays the smooth, planispiral shell structure typical of the genus, with its graceful whorls and natural calcite preservation.

This particular specimen was discovered by our expert field team, Alister and Alison, on 06 October 2024, and was carefully cleaned, prepared, and treated by Alison to reveal its fine detail.

Lytoceras is characterised by its evolute shell with smooth, rounded whorls and wide umbilicus, indicating a fast-moving, nektonic lifestyle. It is an important genus within the family Lytoceratidae, part of the superfamily Lytoceratoidea, and order Ammonitida.

The Beacon Limestone is a Lower Jurassic marine sedimentary unit, indicating deposition in a deepening offshore basin with good oxygenation and conditions suitable for ammonite preservation. These fossils are particularly prized from the Toarcian Stage, which provides insight into marine life following the early Jurassic extinction events.

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.
