Emileia Ammonite Fossil Dorset UK Bajocian Sauzei Zone with COA

Description

Genuine Emileia Ammonite Fossil

This genuine ammonite fossil is identified as Emileia sp. and comes from the Inferior Oolite Group at Milborne Wick, Dorset, UK. It dates to the Bajocian Stage of the Middle Jurassic and is recorded from the Sauzei Zone. This combination of genus, geological unit, biozone, and locality gives the specimen strong scientific and collecting context. The photographs show the exact fossil offered for sale, so the ammonite pictured is the specimen you will receive.

The abbreviation “sp.” indicates that the fossil is confidently identified to the genus Emileia without assigning it to a particular species. This is a standard and careful palaeontological notation, especially useful when preservation displays the principal generic features but does not support a more precise species determination.

Bajocian Age and Sauzei Zone

The Bajocian is a stage within the Middle Jurassic Period. During this interval, warm marine environments covered large areas of what is now southern Britain. Ammonites were abundant and diverse in these seas, and their rapidly changing shell forms make them valuable to geologists for dating and correlating marine sedimentary rocks.

The stated Sauzei Zone provides finer biostratigraphic context within the Bajocian. A biozone is an interval of rock recognised through characteristic fossil assemblages. Ammonites are especially useful for this purpose because many genera and species had relatively short geological ranges and broad distributions. A specimen with named zonal provenance therefore represents a specific interval in Jurassic time as well as an attractive natural object.

Inferior Oolite Group Geology

The Inferior Oolite Group is an important Jurassic succession in southern England. Its marine limestones and associated beds preserve ammonites, bivalves, brachiopods, and other evidence of ancient sea-floor communities. The term oolite refers to limestone that commonly contains small rounded carbonate grains formed in agitated shallow water, although the group includes a range of sedimentary rocks.

Burial within these sediments protected part of the ammonite shell. Compaction, mineralisation, and long-term geological change then produced the fossil visible today. Natural matrix, colour variation, small breaks, mineral veins, and differences in surface texture are genuine elements of this history rather than signs of modern manufacture.

Milborne Wick, Dorset

Milborne Wick is a recognised Dorset fossil locality associated with Jurassic rocks. Provenance to a named collecting area gives this piece greater context than an unlocalised fossil. It can complement a collection organised by ammonite genus, British county, Bajocian biozone, or Inferior Oolite locality.

Dorset is internationally known for its Jurassic geology, and fossils from inland localities add important variety to collections often focused only on coastal sites. This Emileia specimen provides a tangible connection to the ancient marine environments represented by the county’s sedimentary rocks.

Shell Form and Collectable Detail

Emileia ammonites are known for their robust coiled shells and distinctive ornamentation. Examine the photographs for the visible whorls, ribbing, shell outline, and areas of surrounding matrix on this individual piece. The original shell was divided into chambers. The animal lived in the final body chamber, while older sealed chambers contributed to buoyancy control.

The multiple photographs show the specimen from useful angles and provide the clearest record of its preservation and proportions. Every fossil is unique, and the combination of shell detail, matrix, and mineral character makes this a one-of-a-kind geological object.

Exact Specimen, Size and Authenticity

Full sizing is shown in the photographs, which provide the best scale information for this individual fossil. The images are not stock photographs and do not represent a similar example. They show the exact Emileia sp. ammonite supplied to the buyer.

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 identifiable ammonite form, Sauzei Zone context, Inferior Oolite provenance, and Dorset locality. It makes an engaging addition to a cabinet collection, educational display, office, study, or gift for anyone interested in authentic British Jurassic fossils.
