Description
Ludwigia murchisonae Ammonite Fossil from Dorset
Genuine Middle Jurassic Specimen
This listing is for the exact Ludwigia murchisonae ammonite fossil shown in the photographs. It is a genuine natural specimen from Bridport, Dorset, UK, preserved in the Inferior Oolite Group and dating to the Aalenian Stage of the Middle Jurassic. The fossil has been carefully selected and individually photographed, so the specimen pictured is the actual piece you will receive. Please use the sizing photograph for full measurements and examine every image for its precise condition, colour, matrix and surface detail.
Aalenian Geology and the Inferior Oolite
The Aalenian Stage spans approximately 174 to 170 million years ago and forms the earliest part of the Middle Jurassic. Southern Britain was then influenced by warm marine conditions. Sand, carbonate mud, iron-rich grains and other sediments accumulated in shallow seas and were eventually transformed into the varied rocks of the Inferior Oolite Group.
The Bridport area forms part of Dorset’s internationally important Jurassic landscape. Fossils from these strata record the animals that lived in ancient marine ecosystems and help reveal changes in sea level, sediment supply and water depth. A specimen with named species, locality and geological unit retains valuable scientific context as well as visual appeal.
About Ludwigia murchisonae
Ludwigia is an extinct genus of ammonoid cephalopod. Ammonites were marine molluscs with spirally coiled, chambered shells and are related within the wider cephalopod group to living squid, cuttlefish and nautiluses. The animal lived in the final body chamber, while earlier chambers separated by septa helped regulate buoyancy.
Ludwigia murchisonae is a characteristic Aalenian ammonite and is closely associated with biostratigraphic study of this interval. Its shell shows successive whorls and distinctive ribbing, creating the sculptural spiral form valued by fossil collectors. Natural preservation can expose different parts of the shell, and the photographs accurately show the morphology, mineral tones, remaining matrix and completeness of this individual fossil.
Scientific and Collecting Interest
Ammonites evolved rapidly and were widely distributed through Jurassic seas. Because particular species are associated with limited geological intervals, geologists use them as index fossils to compare rock layers and establish relative ages. Ludwigia murchisonae is especially significant in discussions of Aalenian strata, making a correctly provenanced example an educational record of Jurassic time.
This fossil is suitable for a palaeontology collection, geology teaching display, natural history cabinet or distinctive gift. Its recognisable coiled form makes it attractive for display, while the Bridport locality and Inferior Oolite provenance give it a meaningful connection to Dorset’s geological heritage.
Exact Fossil and Authenticity
You will receive the exact specimen pictured, not a stock photograph or substitute. Fossils are natural objects and may retain ancient fractures, matrix, mineral variation, weathering or preparation marks that form part of their authentic history. Review the photographs carefully and use the sizing image for dimensions.
A generic Certificate of Authenticity card with a lifetime guarantee is included. The fossil will be packed carefully for safe transit and protection of the condition shown.
