RARE Pleuroceras spinatum Ammonite Cluster Fossil – Lower Lias Formation, Jurassic Period – Unterstürmig, Germany – Alice Purnell Collection

Original price was: £48.00.Current price is: £43.20.

This listing features a beautiful cluster fossil of the ammonite species Pleuroceras spinatum, originating from the Lower Lias Formation of the Jurassic Period, approximately 190 to 183 million years ago. This exceptional multi-ammonite specimen comes from Unterstürmig, Germany, a site well-known for its richly fossiliferous Lower Jurassic marine strata. The fossil was part of the prestigious Alice Purnell Collection, known for high-quality and scientifically significant specimens.

Pleuroceras spinatum is one of the most iconic species of Early Jurassic ammonites, belonging to the family Amaltheidae. It is characterised by its strong radial ribbing and distinctive spinose (spiny) keel. These ammonites are excellent biostratigraphic markers for the Upper Pliensbachian (Spinatum Zone) and are highly prized among fossil collectors.

This cluster contains multiple specimens on a single matrix, showcasing the natural accumulation and preservation typical of marine seabeds. Each ammonite is preserved in detail, with visible ribbing and keels, giving the piece both aesthetic and scientific appeal.

Geological Context: The Lower Lias Formation, part of the European Lias Group, was deposited in shallow marine environments during the Early Jurassic. These strata, particularly in Bavaria and Franconia, are known for their exceptional fossil preservation, especially of ammonites. Unterstürmig, Germany is a historic locality that has produced some of the finest examples of Pleuroceras ammonites found in Europe.

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.
