Aioloceras Fossil Ammonite | Albian Cretaceous | Madagascar | Genuine Certified Specimen

£24.00

This is a beautifully preserved Aioloceras Fossil Ammonite, originating from the Albian Stage of the Lower Cretaceous period, discovered in the well-known fossiliferous marine layers of Madagascar.

Aioloceras is an elegant genus of ammonite, belonging to the heteromorph ammonites group, known for its uncoiled or loosely coiled shell structure. This specimen represents a superb example of Albian cephalopod evolution, displaying distinct features in its ribbing and ornamentation.

All of our Fossils are 100% Genuine Specimens & come with a Certificate of Authenticity.

The image displays the actual specimen you will receive, with a scale rule and 1cm cube included for accurate measurement. Please refer to the photo for full sizing.

 

Geological and Taxonomic Information:

  • Genus: Aioloceras
  • Fossil Type: Ammonite (extinct marine cephalopod)
  • Age: Lower Cretaceous, Albian Stage (~113 to 100.5 million years ago)
  • Location: Madagascar
  • Formation: Likely Mahajanga Basin marine limestone and marl beds
  • Depositional Environment: Warm, shallow marine shelf with carbonate-rich sedimentation
  • Geological Stage: Albian

 

Taxonomic Classification:

  • Order: Ammonitida
  • Superfamily: Ancyloceratoidea
  • Family: Turrilitidae
  • Genus: Aioloceras
  • Formally Described By: Hyatt, 1900

 

Morphology & Notable Features:

  • Distinct heteromorph coiling with loosely coiled to uncoiled whorls
  • Fine ribbing along the shell, sometimes with subtle tuberculation
  • Shell displays early evolutionary traits seen in turrilitid lineage
  • Highly desirable for its unique form and well-preserved detail

 

Scientific & Collector Significance:

Aioloceras ammonites serve as important indicators of mid-Cretaceous heteromorph diversity. Their unusual coiling makes them stand out in fossil collections, and specimens from Madagascar are known for their excellent preservation and preparation quality.

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.
