Description
Identification and Geological Context
This listing presents a rare Mariella cenomanensis heteromorph fossil ammonite, identified as Cenomanian and Cretaceous. The specimen is associated with SEINE MARITM, France, and comes from the Alice Purnell Collection. Mariella cenomanensis is a named ammonite identification, while “heteromorph” describes an ammonite form whose shell arrangement differs from the more tightly coiled shapes commonly associated with many ammonites.
Ammonites were extinct marine cephalopods that lived in ancient seas and are widely collected for their distinctive shell forms and geological significance. Their fossils are valued because they can combine striking natural morphology with useful information about the rocks and marine environments in which they were preserved. The Cenomanian is a recognised interval within the Cretaceous Period, making this identification relevant to collectors interested in Cretaceous fossils, ammonite diversity and palaeontology.
Collector Interest
This Mariella cenomanensis specimen is suited to fossil collectors seeking an identifiable heteromorph ammonite, a Cretaceous fossil, or a display piece connected with French fossil localities. Its appeal lies in the combination of a specific taxonomic name, Cenomanian Cretaceous age designation and heteromorph ammonite classification. It may also be of interest to students, educators and anyone building a themed collection of ammonites or Cretaceous palaeontological specimens.
The supplied identification is the central feature of this piece. The genus and species name can be used when cataloguing the specimen, while the Cenomanian designation provides its geological context. The locality information associates it with SEINE MARITM, France, as supplied for this specimen. These details make it suitable for a labelled fossil display or a personal reference collection.
