Raw Opalescent Ammonite from Madagascar (30–40 mm) – Cretaceous Fossil
We offer an original, raw ammonite fossil sourced from the famous paleontological sites in Madagascar. This specimen represents the fauna of the Cretaceous period (approximately 100 million years old). The shell has retained its natural mother-of-pearl, which exhibits an opalescent (iridescent) effect, casting light reflections in daylight.
Paleontological specifications and parameters:
- ✓ Taxon: Ammonites (Ammonoidea – cephalopods)
- ✓ Origin: Madagascar
- ✓ Geological age: Cretaceous (approx. 100 million years)
- ✓ Size range: 30–40 mm (shell diameter)
- ✓ Unit of sale: 1 piece
- ✓ Finish: Unpolished, with preserved natural nacre layer
- ✓ Uses: Collectibles, paleontology, educational material
- ✓ Sales policy: Random selection. The photos show sample pieces from the available batch
Geological context and preservation characteristics
Ammonites are extinct cephalopods that dominated the Mesozoic seas. Deposits in Madagascar are renowned for the exceptional state of preservation of the fossils, where processes of phosphatization and mineralization of the shells have preserved delicate structures and the original iridescence of the nacre. These specimens serve as valuable educational material and classic additions to fossil collections.
Sales Information
The purchase includes 1 ammonite specimen, selected at random from our imported batch. The degree of opalescence, the exact shade, and the arrangement of the whorls may vary slightly depending on the specific specimen, which is a natural characteristic of paleontological material.
