RARE 5.5″ Cunningtoniceras inerm Fossil Chalk Ammonite – Middle Cenomanian, Cretaceous – France – Alice Purnell Collection

Description

Featured here is a rare and scientifically valuable fossil ammonite of the species Cunningtoniceras inerm from the Middle Cenomanian Stage of the Late Cretaceous period, dating to approximately 98–95 million years ago. This beautifully preserved specimen, measuring approximately 5.5 inches, was discovered in France and comes from the reputable Alice Purnell Collection, known for its high-quality and well-documented fossil specimens.

Cunningtoniceras inerm is a species of ammonite belonging to the family Acanthoceratidae, characterised by its generally smooth and compressed shell with faint or absent tubercles. Its relatively simple yet elegant morphology makes it distinct among more heavily ornamented contemporaries. These cephalopods lived in warm, shallow marine environments, where they thrived as active swimmers and predators in Cretaceous seas.

The fossil is preserved in the fine white chalk matrix typical of Cenomanian marine deposits, with well-defined coiling and sutures visible across the specimen. It serves both as a striking display item and an important scientific piece.

Geological Context: The Cenomanian Stage is the first stage of the Late Cretaceous period and is marked by high global sea levels and extensive chalk deposition in Europe. France, especially regions with access to fossiliferous chalk formations, is well-known for yielding well-preserved marine invertebrates such as ammonites. Fossils like Cunningtoniceras inerm are valuable for their stratigraphic importance and paleoecological insight.
