RARE Spiroceras bifurcati Fossil Heteromorph Ammonite Jurassic Coast Dorset UK COA

This listing features a VERY RARE fossil specimen of the heteromorph ammonite Spiroceras bifurcati, discovered by our expert field team, Alister and Alison, on 30 April 2025 at Burton Bradstock, along the internationally recognised Jurassic Coast, Dorset, UK.

The fossil originates from the Inferior Oolite Formation, part of the Bajocian Stage of the Middle Jurassic (~170 million years ago). Spiroceras is a highly unusual ammonite genus due to its heteromorph coiling pattern—the shell does not coil in a regular spiral but instead shows a partially uncoiled, irregular or spiral form. This unique morphology makes it an exceptional and highly sought-after specimen.

Scientific and geological context:

Order: Ammonitida

Superfamily: Stephanoceratoidea

Family: Possibly Tulitidae (classification debated)

Genus & Species: Spiroceras bifurcati

Morphology Features: Bifurcating ribbing, heteromorphic shell with open, loosely coiled whorls

Geological Stage: Bajocian

Depositional Environment: Shallow marine shelf with oolitic sedimentation typical of the Inferior Oolite

The fossil has been professionally cleaned, prepped, and treated by Alison, preserving its rare and delicate form. The photo provided is of the actual specimen you will receive, and includes a 1cm scale cube for accurate sizing—please refer to the photo for full measurements.

All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity (COA), confirming provenance and scientific identity.

This is a highly collectable and visually striking piece, ideal for fossil enthusiasts, advanced collectors, museums, or educational institutions looking to showcase rare Jurassic marine life.

This is actually an art piece.

It is intended as a fantastical exhibit rather than a genuine preserved creature. It highlights the artistry of taxidermy and the folklore around werewolves.

The exhibit was made around 2017, for the opening of the Museum Obscurum in Nykøbing Falster, and features a collection inspired by the fictional works of artist Alex CF, including the Merrylin Cryptid Collection. This collection is designed to resemble a historical archive of strange and mythical creatures, blending elements of fantasy, science fiction, and folklore.

Some specimens on display are werewolves, vampires, dragons, and other fantastical beings, along with items such as preserved fossils, maps, and journals supposedly documenting these discoveries.

Many pieces incorporate Victorian aesthetics and scientific tools to make them seem authentic to the era.

It’s a prime example of how art can blur the lines between reality and imagination

Sea Monster in a Moroccan Mine?

The recent unearthing of an alleged sea monster fossil in Morocco's Khouribga province has generated both excitement and significant skepticism within the paleontological community. The specimen, initially heralded as a new species of mosasaur named Xenodens calminechari, features peculiar dental characteristics that deviate dramatically from known tetrapod morphology. Such extraordinary claims demand extraordinary evidence, and in this case, the evidence appears increasingly problematic.

The fossil's most contentious feature is its supposedly unique saw-like tooth structure, which contradicts established understanding of mosasaur dentition. Multiple experts have identified troubling anomalies, including the unprecedented presence of double teeth in single sockets and unusual overlap patterns. These irregularities, combined with the specimen's origin in a region notorious for fossil modification, raise serious red flags about its authenticity.

The timing of this discovery coincides with increasing market pressure for spectacular fossil specimens, particularly from Morocco's phosphate mines. The commercial value of unusual or extreme variations often tempts sellers to enhance or modify fossils, creating a perfect storm of financial motivation and opportunity for fraud. The local history of fossil manipulation for profit cannot be ignored when evaluating this find.

Leading paleontologists, including Henry Sharpe from the University of Alberta, have called for more rigorous examination using advanced imaging techniques. Their preliminary analysis suggests several inconsistencies with known mosasaur tooth replacement patterns. The specimen's composition and structure appear to diverge significantly from verified mosasaur fossils, suggesting possible artificial modification or complete fabrication.

The implications of this controversy extend beyond this single specimen, potentially undermining confidence in paleontological research and specimen authentication processes. If confirmed as a forgery, this case would necessitate not only the retraction of previous publications but also a comprehensive review of authentication protocols. The incident highlights the crucial need for skepticism and thorough verification in paleontological research.

While definitive conclusions await further investigation, this case serves as a sobering reminder of the challenges facing modern paleontology. The pressure to publish revolutionary findings, combined with the commercial fossil trade's influence, creates an environment where spectacular claims require increasingly stringent verification. As the investigation continues, the scientific community must balance the excitement of potential discoveries with rigorous skepticism and methodological scrutiny.

Enhance your fossil collection with this authentic and beautifully preserved Orthoceras vagans fossil orthocone, originating from the Devonian period and discovered in the renowned Hammar Laghdad site, near Erfoud, Morocco. This striking fossil represents an extinct genus of straight-shelled cephalopods, known for their long, conical shells and fascinating internal chamber structures.

Fossil Type: Orthocone Cephalopod

Species: Orthoceras vagans

Geological Period: Devonian (~419 to 359 million years ago)

Location: Hammar Laghdad, Anti-Atlas Mountains, Morocco

Scale Rule: Squares/Cube = 1cm (See photo for full sizing details)

Specimen: Actual item pictured is the specimen you will receive

Authenticity: All of our fossils are 100% genuine specimens and come with a Certificate of Authenticity

Geological and Paleontological Information

Orthoceras vagans is an extinct nautiloid cephalopod from the Order Orthocerida, which flourished in the world's oceans during the Paleozoic Era. These marine invertebrates had long, straight shells composed of calcite and were divided internally into chambers. The animal inhabited the last chamber, with the earlier chambers used for buoyancy control via a siphuncle running through the center.

Phylum: Mollusca

Class: Cephalopoda

Order: Orthocerida

Family: Orthoceratidae

Superfamily: Orthocerataceae

Geological Stage: Likely from the Emsian to Givetian stages of the Middle Devonian (stratigraphic confirmation not provided)

Depositional Environment: Marine platform setting, part of a shallow epicontinental sea that covered the region; fossil-bearing layers consist mostly of black limestone and mudstone

Morphological Features: Long, straight conical shell (orthocone) with internal chambers; central siphuncle visible in some specimens; external ornamentation may include growth lines and faint ribbing

Notable: Hammar Laghdad is internationally known for its abundant and well-preserved Devonian marine fossils, especially orthocones and trilobites

Biozone: No specific biozone designation without exact stratigraphic layer

Identifier: While Orthoceras was first described in the 18th century, species-level classification such as vagans typically references work by subsequent 19th and early 20th-century paleontologists
