Hypergongoceras sp. iridescent fossil ammonite upper albian cretaceous madagascar genuine specimen

£24.00

Discover an exceptional fossil: an authentic HYPERGONGOCERAS sp. iridescent fossil ammonite, featuring a remarkable natural preservation. This beautiful specimen dates to the Upper Albian Stage of the Early Cretaceous Period (approximately 105 to 100 million years ago) and was found in the renowned fossil beds of Madagascar.

Geology & Origin:

During the Upper Albian, Madagascar’s environment was dominated by shallow tropical seas, perfect for marine life like ammonites. After death, ammonite shells were rapidly buried by fine sediment, and over millions of years, they fossilized. In rare instances like this specimen, the original aragonite layer remained intact, producing a stunning “Mother of Pearl” iridescent sheen that shifts and shimmers in the light.

Fossil Type & Species:

  • Type: Fossil Ammonite (Extinct marine mollusc)
  • Species: Hypergongoceras sp.
  • Preservation: Outstanding, with vivid iridescent mother of pearl

Features:

  • 100% authentic, natural fossil specimen
  • Supplied with a Certificate of Authenticity
  • Personally hand-selected for superior preservation and beauty
  • The exact fossil shown in the photos is the one you will receive
  • Scale rule / cube shown = 1cm: Please refer to listing photos for full sizing

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.
