Morphoceras multiforme Ammonite Fossil Dorset UK Bathonian with COA

Description

Genuine Morphoceras Ammonite Fossil

This genuine ammonite fossil is identified as Morphoceras multiforme and comes from the Fuller’s Earth Formation at West Bay near Bridport, Dorset, UK. It dates to the Lower Bathonian Stage of the Middle Jurassic and is a carefully selected British specimen with useful species, formation, age, and locality information. The photographs show the exact fossil offered for sale, so the ammonite pictured is the specimen you will receive.

Morphoceras multiforme was an extinct marine cephalopod with a chambered, coiled shell. As it grew, the animal added progressively larger chambers around the outer whorl. The living ammonite occupied the final body chamber, while the older sealed chambers helped regulate buoyancy. Ammonites were relatives of living squid, cuttlefish, and nautiluses, although they belonged to their own extinct branch of cephalopods.

Lower Bathonian Geological Age

The Bathonian is a stage within the Middle Jurassic Period. During the Lower Bathonian, marine environments covered parts of southern Britain and supported diverse communities of ammonites and other invertebrates. Shells could become buried in sea-floor sediment, protecting them from complete destruction. Compaction, mineralisation, and geological change then preserved some examples as fossils.

Ammonites evolved rapidly and were distributed over broad marine areas. Their changing forms make them especially useful to geologists for comparing sedimentary sequences and establishing relative ages. The stated Lower Bathonian age gives this specimen a clear position within the Jurassic succession and makes it suitable for a collection arranged by geological stage.

Fuller’s Earth Formation

The Fuller’s Earth Formation is a Middle Jurassic sedimentary unit known from parts of southern England. It includes clay-rich marine deposits laid down in an ancient sea. These sediments preserve evidence of the organisms that lived in or passed through the environment, including ammonites whose shells settled onto the sea floor.

The specimen’s natural matrix, colour, mineral texture, and any small irregularities reflect its history of burial and fossilisation. Natural breaks, mineral veins, areas of surrounding rock, or differences in surface preservation are genuine characteristics of the fossil rather than features of a manufactured replica.

West Bay and Bridport, Dorset

West Bay lies on the Dorset coast near Bridport, within a region internationally known for its Jurassic geology. Fossils with documented locality information have particular value because their place of origin connects them to a recognisable geological succession. This example can complement a collection organised by ammonite genus, British county, Jurassic stage, or formation.

The Dorset coast provides dramatic exposures of sedimentary rocks, but every individual fossil records its own history of preservation. The photographs show the actual combination of shell detail and matrix on this specimen and provide useful views of its condition and proportions.

Shell Form and Collectable Detail

Morphoceras ammonites are studied through their coiling, whorl proportions, and shell ornamentation. Examine the photographs for the visible ribs, whorls, outer-shell form, and preserved surface details on this individual piece. These features are among the morphological characteristics used when comparing ammonites and interpreting their growth.

Full sizing is shown in the photographs, which provide the clearest scale information for the fossil. The images are not stock photographs and do not represent a similar example. They show the exact Morphoceras multiforme ammonite that will be supplied.

Authenticity and Presentation
