Introducing an exceptional NEOSILESITES AMBATOLAFTENSIS iridescent fossil ammonite, adorned with an incredible natural Mother of Pearl shell finish. This beautiful fossil originates from the Lower Albian Stage of the Early Cretaceous Period (approximately 113 to 110 million years ago), discovered in the renowned fossil beds of Mitsinjo, Madagascar.

Geology & Origin:

During the Lower Albian, Mitsinjo was submerged beneath warm shallow seas, creating ideal conditions for marine life like ammonites to thrive. After death, these ammonites were buried by fine sediments and fossilized over millions of years. Rarely, the original aragonite layer survived fossilization, leading to the breathtaking iridescent “Mother of Pearl” effect seen on this piece.

Fossil Type & Species:

  • Type: Fossil Ammonite (Extinct marine mollusc)
  • Species: Neosilesites ambatolaftensis
  • Preservation: Outstanding, with vivid, colorful mother of pearl iridescence

Features:

  • 100% genuine, natural fossil specimen
  • Comes with a Certificate of Authenticity
  • Carefully selected for quality and iridescence
  • The exact specimen shown in the listing photographs
  • Scale rule / cube shown = 1cm: Full sizing visible in photo

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.
