Rare Dissoceras Ammonite Fossil from the Middle Bajocian Jurassic Period, Burton Bradstock UK

Detailed Description

Authentic Jurassic Ammonite from Burton Bradstock

This listing is for a genuine Dissoceras ammonite fossil from the Middle Bajocian stage of the Jurassic Period (approximately 170–168 million years old). It was discovered in the well-known fossil-rich deposits of Burton Bradstock, Dorset, United Kingdom, part of the classic Jurassic Coast World Heritage Site. Each specimen is carefully chosen for its quality and authenticity and comes with a Certificate of Authenticity. The photographs provided show the actual fossil you will receive, with a 1 cm scale cube included for precise sizing.

Geological Setting and Age

The Middle Bajocian stage is a subdivision of the Jurassic Period, representing a time when shallow epicontinental seas dominated much of Europe. The sediments around Burton Bradstock consist primarily of Jurassic clays, shales, and limestones, which provided the ideal conditions for the preservation of ammonites and other marine organisms. These fossil-bearing layers have long been studied for their scientific importance, offering insight into Jurassic marine biodiversity and paleoenvironmental changes.

Morphology and Features of Dissoceras

The genus Dissoceras is an important representative of Jurassic ammonites within the order Ammonitida and the superfamily Stephanoceratoidea. Characteristic features of Dissoceras ammonites include:

• Moderately evolute coiling, meaning the whorls are visible and not deeply overlapping.
• Distinctive ribbing patterns running across the shell flanks, which sometimes bifurcate or curve slightly towards the outer edge.
• A rounded or keeled venter, aiding hydrodynamics in the ancient seas.
• Intricate suture lines, a hallmark of ammonites that reflect their evolutionary complexity.

These features make Dissoceras both a visually appealing fossil and an important taxonomic marker for geologists and paleontologists.

Stratigraphic and Scientific Importance

Ammonites such as Dissoceras serve as index fossils, used to define and correlate strata across wide geographic regions. Their rapid evolutionary changes mean they are invaluable for dating rocks of Middle Jurassic age. Specimens from Burton Bradstock contribute to the detailed stratigraphy of the British Jurassic Coast and allow scientists to compare faunal assemblages between the UK and other global Jurassic deposits.

Collectible and Display Qualities

This Dissoceras ammonite fossil is not only a scientifically significant specimen but also an aesthetically pleasing collector’s piece. The natural ribbing and spiral geometry of the shell create a striking display, making it a desirable addition to any fossil collection, educational setting, or museum display. Its provenance from Burton Bradstock adds to its rarity and historical value, as fossils from this iconic locality are highly prized among collectors.
