RARE: 3.5″ Beudantiella cophinoceras Fossil Ammonite | Albian Cretaceous | Madagascar | Certified Authentic Specimen

Description

This is a RARE 3.5″ Beudantiella cophinoceras Fossil Ammonite, a stunningly preserved and scientifically significant specimen from the Albian Stage of the Lower Cretaceous, originating from the fossil-rich marine strata of Madagascar.

Beudantiella cophinoceras is a less commonly encountered genus of heteromorph ammonite, appreciated for its elegant coiling, shell compression, and complex suture patterns. This specimen demonstrates classic morphological features of the genus and is a superb representation of Albian marine faunas.

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

Geological and Taxonomic Information:

• Species: Beudantiella cophinoceras
• Fossil Type: Ammonite (extinct marine cephalopod)
• Age: Lower Cretaceous, Albian Stage (~113 to 100.5 million years ago)
• Locality: Madagascar
• Formation: Likely Mahajanga Basin marine carbonate deposits
• Depositional Environment: Shallow marine shelf with high bioclastic sedimentation in a warm, subtropical sea
• Geological Stage: Albian

 

Taxonomic Classification:

• Order: Ammonitida
• Superfamily: Desmoceratoidea
• Family: Beudanticeratidae
• Genus: Beudantiella
• Species: B. cophinoceras
• Formally Described By: Breistroffer, 1947

 

Morphology & Notable Features:

• Slightly involute, compressed shell with weak to moderate ribbing
• Subcircular to oval whorl section
• Finely detailed suture lines with lobes and saddles characteristic of early desmoceratids
• Rare and regionally significant fossil with distinct features, ideal for display or reference

 

Scientific & Collector Significance:

Beudantiella ammonites are excellent biostratigraphic indicators within the Albian and offer insight into mid-Cretaceous cephalopod evolution. Madagascar’s fossil beds yield some of the best-preserved examples, and this particular species is especially sought-after due to its scarcity in commercial collections.
