Description
**Rare A-Grade Coltraneia oufatenensis Trilobite Fossil**
This genuine Coltraneia oufatenensis is a rare A-grade trilobite fossil from Ofaten, Morocco. It dates to the Lower Devonian, more than 400 million years ago, when this part of North Africa lay beneath a warm sea along the northern margin of the ancient continent Gondwana. Carefully selected for its quality, uncommon identity and display appeal, this is the exact fossil specimen shown in the photographs. The images allow you to inspect its preservation, preparation, matrix and natural colour before purchase. Please refer to the photographs for full sizing.
**Lower Devonian Geology of Ofaten**
During the Lower Devonian, marine sediment accumulated across the seabed of what is now south-eastern Morocco. These environments supported varied communities of trilobites, brachiopods, corals, crinoids, molluscs and cephalopods. Fine sediment and carbonate mud created suitable conditions for the burial and preservation of mineralised exoskeletons.
After this trilobite died, its remains became buried within seabed sediment. Burial helped protect the exoskeleton from complete destruction. Compaction, mineral replacement and chemical alteration gradually transformed the surrounding sediment into rock and preserved the fossil. Later geological uplift and erosion exposed the fossil-bearing strata, allowing the specimen to be discovered and carefully prepared from its matrix.
**Distinctive Coltraneia Morphology**
Coltraneia is a phacopid trilobite known for a strongly sculpted exoskeleton and prominent visual features. Its body follows the classic trilobite plan, divided lengthways into a central axial lobe and two pleural lobes and crossways into a cephalon, articulated thorax and pygidium. Coltraneia oufatenensis has an especially striking appearance that makes it highly desirable among collectors of Moroccan trilobites.
The cephalon carries large compound eyes that helped the living animal detect light and movement across a broad field of view. Phacopid eyes are famous for their specialised calcite lenses, an important evolutionary adaptation in ancient arthropods. The raised glabella protected important organs, while the articulated thoracic segments provided flexibility for movement over or within the seabed.
Articulation also permitted defensive enrolment, bringing the armoured head and tail regions together to protect the softer underside from predators and physical disturbance. The combination of conspicuous eyes, strong axial definition and segmented body gives this fossil both scientific interest and dramatic display character.
**Rare Collector Fossil and Educational Display**
This Coltraneia oufatenensis is suitable for an advanced fossil cabinet, specialist trilobite collection, museum-style display or educational resource. Its rare species identity and Ofaten provenance make it especially appealing to collectors seeking an unusual Lower Devonian Moroccan trilobite. The specimen can also illustrate arthropod segmentation, compound-eye evolution, defensive enrolment and adaptation within ancient marine ecosystems.
As a genuine fossil excavated and prepared from rock, the specimen may show natural matrix, mineral staining, fine cracks, small chips, preparation marks, stabilised or restored areas and variations in surface texture. These characteristics are normal for prepared trilobites and form part of the fossil’s individual geological and collecting history. The photographs document the actual piece supplied rather than a stock example.
**Certificate of Authenticity**
Your Coltraneia oufatenensis fossil includes a generic Certificate of Authenticity card with a lifetime guarantee. The certificate confirms that the specimen is a genuine fossil and records its supplied geological age and provenance. Its rare identity, authentic Lower Devonian age, Ofaten origin, A-grade presentation and certification make it an outstanding addition to a collection of Moroccan trilobites, prehistoric arthropods or ancient marine life.
