Leptosphinctes festensis Ammonite Fossil Jurassic Bajocian Concavum Zone Dorset UK

£120.00

This genuine ammonite fossil is a beautifully preserved specimen of Leptosphinctes festensis, discovered in the Inferior Oolite Formation at Louse Hill, near Beaminster, Dorset, UK. Dating back to the Bajocian stage of the Middle Jurassic (approx. 170 million years ago), this fossil comes from the Concavum Zone, a notable biostratigraphic interval for the identification and correlation of Jurassic marine sequences.

Leptosphinctes ammonites are known for their evolute shells with strong ribbing and relatively compressed whorls, features well-represented in this specimen. The species festensis was formally described in 1902 by Wetzel, and it serves as a useful marker fossil within the Bajocian.

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.
