This listing features a RARE and impressive 17″ Lytoceras Fossil Ammonite, sourced from the Ait Ouarhitane Formation near Alnif, Morocco, a globally recognised site for Jurassic marine fossils.

Lytoceras is a genus of extinct ammonite molluscs from the family Lytoceratidae, belonging to the superfamily Lytoceratoidea and the order Ammonitida. This genus is well-known for its distinctive, loosely coiled, evolute shells and highly ornamented whorls. These cephalopods thrived in the oceans during the Jurassic Period, particularly from the Toarcian to Callovian stages, and are often interpreted as fast-moving nektonic carnivores.

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.
