Description 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.
