HAMULINA ALPINA Fossil Heteromorph Ammonite – Barremian, Cretaceous – Alp de Provence, France

About the Fossil:

This exceptionally preserved Hamulina alpina heteromorph ammonite fossil originates from the Barremian stage of the Early Cretaceous period (~129-125 million years ago) and was discovered in Alp de Provence, France. Hamulina is a genus of heteromorph ammonites, recognized for their uncoiled, elongated shells with a unique curved morphology, differing from the more common tightly coiled ammonites.

During the Early Cretaceous, heteromorph ammonites like Hamulina alpina thrived in shallow marine environments, floating in ancient seas. Their distinctive shell shape suggests adaptations for neutral buoyancy and specialized swimming behavior, likely drifting along ocean currents to feed on plankton. The Barremian deposits of Alp de Provence are well known for their diverse marine fossils, including ammonites, bivalves, and gastropods, providing valuable insights into prehistoric marine ecosystems.

Description

HAMULINA ALPINA Fossil Ammonite

This Hamulina alpina fossil is a heteromorph ammonite from the Barremian stage of the Cretaceous. Its distinctive identification makes it an appealing addition to fossil collections focused on ammonites, Cretaceous palaeontology and the varied forms of ancient marine life. The specimen is associated with Alp de Provence, France, and comes from the Alice Purnell Collection.

Identification and Geological Context

Hamulina alpina is identified here as a heteromorph ammonite. Unlike the more familiar tightly coiled ammonites, heteromorph ammonites are known for their unconventional shell forms, which can include open coils, hooks, curves and other less uniformly spiral shapes. These unusual morphologies are an important part of ammonite diversity and make heteromorph specimens particularly interesting for collectors and students of palaeontology.

The specimen is identified as Barremian in age, placing it within the Cretaceous Period. The Barremian was a time of substantial marine fossil diversity, and ammonites are among the most useful and recognisable fossil groups from Cretaceous marine deposits. Their shells and distinctive forms provide an engaging connection to the changing marine ecosystems of the ancient past.

Locality and Collection

The stated locality for this fossil is Alp de Provence, France. French Cretaceous fossil material is valued by collectors for its connection to the rich geological history of the region and its record of ancient marine organisms. This specimen is from the Alice Purnell Collection, adding a collection-specific context for display, study or continued curation.

Collector Appeal

With its named identification, heteromorph ammonite classification, Barremian age and French locality, this fossil is well suited to a range of collecting interests. It can be displayed as a natural history specimen, included in an ammonite or Cretaceous fossil collection, or used as a conversation piece for anyone interested in palaeontology and historical geology. The Hamulina alpina identification also makes it a distinctive choice for collectors seeking ammonites beyond the conventional planispiral shell forms.
