Discover a breathtaking specimen: an authentic DESMOCERAS VALEDORSELLA OKUSCHENSIS iridescent fossil ammonite, preserved with exquisite Mother of Pearl shell detail. This remarkable fossil dates back to the Aptian Stage of the Early Cretaceous Period (approximately 125 to 113 million years ago) and was discovered in the renowned fossil beds of Tulear, Madagascar.

Geology & Origin:

Tulear, Madagascar, was once covered by warm, shallow seas, perfect for ammonites to flourish during the Aptian age. Upon death, their shells were quickly buried under fine sediments, preserving their intricate structures. In rare cases such as this, the nacreous aragonite layer fossilized intact, resulting in the stunning iridescent “Mother of Pearl” effect that radiates shimmering colors when exposed to light.

Fossil Type & Species:

  • Type: Fossil Ammonite (Extinct marine cephalopod)

Cretaceous Information

The Cretaceous Period (145–66 million years ago) was the final era of the Mesozoic, marked by the dominance of dinosaurs and the rise of flowering plants. It had a warm, greenhouse climate, with high sea levels that created vast shallow inland seas. Marine life flourished, including mosasaurs, ammonites, and rudist reefs, while the land was ruled by iconic dinosaurs like Tyrannosaurus rex, Triceratops, and Spinosaurus. Mammals and birds diversified, and insects thrived. The period ended with the mass extinction event, likely caused by an asteroid impact, wiping out the dinosaurs and paving the way for the rise of mammals in the Cenozoic.
