PLANAMMATOCERAS OBTECUM Fossil Ammonite Jurassic Inferior Oolite Dorset UK

£36.00

This listing features a well-preserved ammonite fossil of Planammatoceras obtecum, discovered at Burton Bradstock along the world-renowned Jurassic Coast in Dorset, United Kingdom. This specimen originates from the Inferior Oolite Group, a Middle Jurassic marine limestone formation notable for its rich fossil assemblage.

Planammatoceras obtecum belongs to a group of ammonites characterised by fine ribbing and compressed, involute shells. These elegant fossils are less commonly found than other ammonites from the Inferior Oolite, making this a particularly notable piece for collectors.

Geological & Scientific Details:

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.
