Algerites ellipticus Heteromorph Ammonite Fossil Albian Kent UK with COA

Description

This listing is for the exact genuine fossil shown in the photographs: an Algerites ellipticus heteromorph ammonite from the Gault Clay Formation at Folkestone, Kent, United Kingdom. It dates from the Middle Albian stage of the Early Cretaceous Period and is supplied with our lifetime Certificate of Authenticity. The certificate records the fossil identification, geological unit, age and locality, giving you a permanent reference for your collection.

Algerites is an unusual heteromorph ammonite, belonging to a remarkable group of Cretaceous cephalopods whose shells departed from the familiar flat, tightly coiled ammonite form. The shell geometry of heteromorphs could include open coils, curved shafts and hooked sections as the animal developed. Algerites ellipticus is valued by collectors for this distinctive growth form and for its place within the diverse ammonite fauna of the Gault Clay. Specimens provide an engaging illustration of the evolutionary experimentation that occurred among Cretaceous ammonites.

The Gault Clay Formation is one of Britain’s classic fossil-bearing marine deposits. At Folkestone, dark clay was laid down on a relatively quiet seabed while southeastern England lay beneath the sea. Fine sediment settled through the water and buried shells and other remains, sometimes preserving delicate features that would be lost in a higher-energy environment. The formation is famous for ammonites and also yields bivalves, gastropods, crustaceans and other marine fossils. Its rich fauna has made Folkestone an internationally recognised locality for studying the Early Cretaceous.

The Middle Albian falls within the later part of the Early Cretaceous, roughly around 110 to 105 million years ago. Sea levels were rising and broad marine environments extended across parts of Europe. Ammonites were active cephalopod molluscs related to living squid, cuttlefish and nautiluses. The chambered part of the shell helped regulate buoyancy, while the animal occupied the final body chamber. Heteromorph shell shapes may have influenced how these animals moved and oriented themselves in the water, making them particularly interesting subjects for palaeobiological study.

Because ammonite lineages evolved rapidly and many species were distributed across wide regions, palaeontologists use them as index fossils to correlate and date marine strata. A specimen with a reliable species, formation, stage and locality therefore carries scientific context as well as visual appeal. This Algerites ellipticus is a tangible record of an ancient marine ecosystem and of the geological history preserved in the cliffs around Folkestone.

Please examine every photograph carefully, as the images form an essential part of the description. You will receive the exact fossil pictured, not a stock image or a similar substitute. Natural matrix, surface texture, colour variation, incomplete shell areas, mineral deposits and small imperfections are normal features of a genuine fossil and are shown honestly. For full sizing and proportions, please refer to the measuring reference visible in the photographs.

This fossil would suit a collector of British ammonites, Gault Clay fossils, heteromorph cephalopods or Early Cretaceous life. Its unusual shell form also makes it a useful educational specimen for explaining ammonite diversity, growth and marine adaptation. It would make a thoughtful gift for a fossil enthusiast, geology student or natural history collector.

The specimen will be packed carefully for dispatch. Handle it gently and keep it in a stable, dry display environment. The included generic lifetime Certificate of Authenticity identifies it as Algerites ellipticus, records the Gault Clay Formation and Middle Albian age, and gives Folkestone, Kent, UK as the locality. This is a genuine natural fossil with scientific, historic and display interest.
