Description
CRIOCERAS MAJORIENSIS Fossil Ammonite
This fossil is identified as Crioceras majoriensis, a heteromorph ammonite from the Lower Barremian of the Cretaceous. Ammonites were extinct marine cephalopods related to modern nautiluses, squid and cuttlefish. Their fossilised shells are highly valued by collectors because they preserve an important record of ancient marine life and changing environments through geological time.
Identification and Geological Context
Crioceras majoriensis is presented here as a heteromorph ammonite. The term “heteromorph” is used for ammonites with shell forms that differ from the more regularly coiled planispiral shapes often associated with classic ammonite fossils. These unusual forms are of particular interest to collectors because ammonite shell architecture can vary considerably between groups and geological intervals.
The specimen is assigned to the Lower Barremian, a subdivision of the Early Cretaceous within the wider Cretaceous Period. This geological age places the fossil within a significant chapter of Mesozoic history, when ammonites were widespread in marine environments and evolved into a diverse range of shell forms. The supplied location is the Alps, France.
Collector Interest
A Crioceras majoriensis fossil is an appealing addition to collections focused on ammonites, heteromorph ammonites, Cretaceous fossils or historically significant marine invertebrates. Its scientific interest comes from the combination of a named fossil identification, an Early Cretaceous age assignment and a heteromorph ammonite classification. It may also suit geology displays, fossil education collections and natural history presentations centred on ammonite diversity.

Collection and Authentication
From the Alice Purnell Collection
This Fossil is a genuine specimen and Includes a Certificate of Authenticity lifetime guarantee generic card.
The included certificate wording provides an additional record for display and collecting purposes. The specimen is offered as a named Crioceras majoriensis heteromorph ammonite from the Lower Barremian, Cretaceous, associated with the Alps, France. It is suitable for collectors seeking a distinctive ammonite fossil with clear geological context and a documented collection association.
Display and Educational Use
This fossil can be used as a conversation piece in a home collection, classroom geology display, museum-style cabinet or natural history study. It offers an accessible way to explore ammonite evolution, fossil identification and the geological timescale. The Lower Barremian designation also makes it useful for comparing fossils from different intervals of the Cretaceous and for introducing the diversity of extinct marine cephalopods.
