Description
Neocardioceras juddii Ammonite Fossil
This genuine Neocardioceras juddii ammonite fossil is a carefully selected Cenomanian specimen from Glynde, East Sussex, UK. Dating to the Upper Cretaceous Period, this fossil represents a fascinating marine cephalopod from the warm shallow seas that once covered much of southern Britain during one of the most important intervals of chalk-sea development.
The fossil shown in the photograph is the actual specimen you will receive. It has been carefully chosen as an individual collectable fossil, making it ideal for ammonite collectors, British fossil enthusiasts, geology students, educational displays, natural history collections, and anyone interested in Cretaceous marine life. Full sizing can be seen in the photo.
Genuine Fossil with Certificate of Authenticity
This fossil is a genuine specimen and includes a Certificate of Authenticity lifetime guarantee generic card. The listing photograph shows the exact fossil supplied, so you can purchase with confidence knowing this is the actual specimen that will be sent.
Ammonites were extinct marine cephalopods related to modern squid, cuttlefish, octopus, and nautilus. Their coiled shells are among the most recognisable fossils in the world, and many ammonite species are highly valued because they help identify and date marine sedimentary rocks. Cretaceous ammonites such as Neocardioceras are especially collectable because they are linked to the extensive chalk-sea environments that developed across Britain and Europe during the Late Cretaceous.
Geology and Age
This specimen dates to the Cenomanian stage of the Upper Cretaceous Period, approximately 100 to 94 million years old. The Cenomanian was a time of high global sea levels, when large areas of what is now southern England were submerged beneath warm marine waters. These seas supported a diverse ecosystem of ammonites, bivalves, echinoids, sponges, fish, marine reptiles, and many other organisms.
The Cenomanian is especially important in British geology because it records the transition into the widespread chalk-forming seas. Fine carbonate-rich sediments accumulated on the sea floor, eventually forming the chalk and associated deposits for which southern England is so well known. Fossils from this interval provide valuable evidence of marine life during a major phase of rising sea levels and environmental change.
Species and Scientific Interest
Neocardioceras juddii is a notable Cenomanian ammonite and is particularly associated with the upper part of the Cenomanian succession. It is an important fossil for collectors interested in Cretaceous ammonite biostratigraphy, as ammonites from this group are used to help recognise and correlate rock layers of similar age.
The genus Neocardioceras belongs to the order Ammonitida and is associated with the superfamily Acanthoceratoidea, a major group of Cretaceous ammonites that includes many ribbed and ornamented forms. Neocardioceras is known for its relatively compact shell form, visible ribbing, and ornamentation that may include raised tubercles or nodes depending on preservation and growth stage. These features give the fossil its distinctive ammonite character and make it appealing as both a display piece and a study specimen.
The species Neocardioceras juddii is significant because it is linked with the well-known Juddii ammonite biozone near the top of the Cenomanian. This makes it a particularly interesting fossil for anyone collecting zonal ammonites, British Cretaceous fossils, or specimens with strong stratigraphic value. Its named species identification adds scientific interest and helps place the fossil within a specific chapter of Upper Cretaceous marine history.
Glynde, East Sussex Locality
This fossil comes from Glynde, East Sussex, UK, a locality within the chalk landscapes of southern England. East Sussex is well known for its Cretaceous geology, with chalk downs and coastal exposures preserving evidence of the ancient seas that covered the region during the Late Cretaceous.
A Cenomanian ammonite from Glynde has strong locality interest for collectors of British fossils, Sussex fossils, chalk fossils, and Cretaceous ammonites. Locality information adds important scientific and collectable value because it connects the specimen to a specific place, age, and geological setting. Fossils from named localities are particularly desirable for organised collections, as they preserve both the natural history of the specimen and its geological provenance.
Display and Collectability
This Neocardioceras juddii ammonite fossil is an excellent addition to a fossil cabinet, educational collection, display shelf, or specialist collection of British Cretaceous fossils. Its Cenomanian age, Glynde East Sussex provenance, named ammonite identification, and genuine Certificate of Authenticity make it a desirable specimen for both new and experienced collectors.
With its connection to the Upper Cretaceous chalk seas and its relevance to Cenomanian ammonite faunas, this fossil is ideal for anyone interested in prehistoric marine life, ammonite evolution, British geology, chalk fossils, or natural history display specimens. Carefully selected and photographed individually, this fossil is supplied exactly as shown, giving you a genuine and well-documented specimen for study, display, or collection.
