Phylloceras andreae Fossil Ammonite – Callovian, Jurassic – Tulear, Madagascar

About the Fossil:

This well-preserved Phylloceras andreae ammonite fossil originates from the Callovian stage of the Middle Jurassic (~166-163 million years ago) and was discovered in Tulear, Madagascar. Phylloceras is a genus of phylloceratid ammonites, known for their smooth, involute shells with highly intricate and complex suture patterns. Unlike ribbed ammonites, these phylloceratids have a more streamlined and hydrodynamic shell, which may have allowed for enhanced swimming efficiency in Jurassic seas.

During the Middle Jurassic, ammonites like Phylloceras andreae thrived in warm marine environments, where they played an essential role in the oceanic food chain. Unlike many other ammonites, phylloceratids are considered deep-water cephalopods, making them particularly valuable for study and collection. The Callovian-aged deposits of Tulear, Madagascar, are renowned for their ammonite-rich formations, offering crucial insights into Jurassic marine life.

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.
