Description
Genuine Hamites Heteromorph Ammonite Fossil
This genuine heteromorph ammonite fossil is identified as Hamites and comes from the Gault Clay Formation at Folkestone in Kent, UK. It dates to the Albian Stage of the Lower Cretaceous and is a carefully selected British specimen with valuable genus, formation, age, and locality information. The photographs show the exact fossil offered for sale, so the piece pictured is the specimen you will receive.
Hamites belonged to the heteromorph ammonites, a distinctive group whose shells did not form the tight continuous spiral familiar in many ammonites. Instead, Hamites developed elongated, curved, or hook-like shell sections. This unusual growth pattern makes the genus immediately recognisable and provides a striking example of the diversity reached by ammonites during the Cretaceous.
Albian Geological Age
The Albian is the final stage of the Early Cretaceous Period. During this interval, marine environments covered much of southern Britain and supported varied ammonites and other sea life. Shells could settle on the sea floor after death and become buried within fine sediment. Compaction, mineralisation, and geological change then preserved some examples as fossils.
Ammonites evolved rapidly and were widely distributed through ancient seas. Their changing shell forms make them particularly useful to geologists for comparing sedimentary sequences and establishing relative ages. The documented Albian age gives this specimen a clear position within the Lower Cretaceous succession.
Gault Clay Formation
The Gault Clay Formation consists largely of fine marine clay deposited in a relatively offshore sea. Its sediments are well known for preserving ammonites and other fossils, sometimes with delicate surface detail. The fine-grained matrix can record ribbing, shell curvature, and other features important for identification.
Burial within the clay protected part of this Hamites shell. The fossil’s natural matrix, colour, mineral texture, small breaks, and differences in preservation reflect its long geological history. These are genuine features of an ancient fossil rather than signs of modern manufacture.
Folkestone, Kent
Folkestone is a classic British fossil locality for the Gault Clay Formation. Coastal exposures in Kent have produced a diverse Albian fauna and are especially associated with ammonites. Provenance to this named site adds meaningful context and makes the specimen suitable for a collection organised by British locality, Cretaceous stage, formation, or heteromorph genus.
Shell Form and Collectable Detail
Hamites fossils commonly preserve curved or shaft-like sections of the original shell. Examine the photographs for the shell outline, rib pattern, curvature, growth features, and natural matrix visible on this individual piece. The ornamentation along the shell can provide important morphological detail.
The original shell was divided into chambers. The living animal occupied the final body chamber, while older sealed chambers contributed to buoyancy control. The unusual uncoiled form raises fascinating questions about orientation and movement in life, making Hamites an engaging fossil for teaching about ammonite adaptation and diversity.
Exact Specimen and Full Sizing
Full sizing is shown in the photographs, which provide the clearest scale and condition information for this individual fossil. The images are not stock photographs and do not represent a similar example. They show the exact Hamites heteromorph ammonite that will be supplied.
Authenticity and Presentation
This is a genuine fossil specimen and includes a generic Certificate of Authenticity card with a lifetime guarantee. It has been carefully chosen for its distinctive heteromorph form, Albian age, Gault Clay provenance, and Folkestone locality. It makes an excellent addition to a cabinet collection, educational display, office, study, or gift for anyone interested in authentic British Cretaceous fossils and unusual ammonites.
