Anacleoniceras iridescent fossil ammonite mother of pearl shell albian cretaceous madagascar genuine

£18.00

Own a dazzling piece of natural history with this authentic ANACLEONICERAS iridescent fossil ammonite, showcasing a stunning Mother of Pearl shell preservation. Dating to the Albian Stage of the Early Cretaceous Period (approximately 113 to 100 million years ago), this beautiful specimen was found in the fossil-rich layers of Madagascar.

Geology & Origin:

During the Albian age, much of Madagascar was submerged beneath warm, shallow seas teeming with marine life. This environment was perfect for ammonites to thrive and eventually become fossilized. Over millions of years, minerals preserved the ammonite shells, sometimes retaining the original aragonite layers that now shimmer with an iridescent “Mother of Pearl” effect.

Fossil Type & Species:

  • Type: Fossil Ammonite (Extinct marine mollusc)
  • Species: Anacleoniceras sp.
  • Preservation: Exceptional, vivid mother of pearl iridescence

Features:

  • 100% genuine, natural fossil specimen
  • Comes with a Certificate of Authenticity

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.
