Ptychophylloceras (Ptychophylloceras) subptychoicum Fossil Ammonite – Oxfordian, Jurassic – Tulear, Madagascar

About the Fossil:

This well-preserved Ptychophylloceras (Ptychophylloceras) subptychoicum ammonite fossil originates from the Oxfordian stage of the Late Jurassic (~163-157 million years ago) and was discovered in Tulear, Madagascar. Ptychophylloceras is a genus of phylloceratid ammonites, characterized by their smooth, involute shells with intricate suture patterns, making them a distinct and scientifically significant ammonite group.

Unlike many other ammonites, phylloceratids like Ptychophylloceras subptychoicum are believed to have been deep-water species, with their streamlined shells suggesting advanced swimming capabilities. Their highly lobed and complex suture lines make them a valuable specimen for researchers and collectors alike. The Oxfordian-aged deposits of Tulear, Madagascar, are recognized for their rich ammonite formations, providing 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.
