Phacops Trilobite Fossil Eifelian Devonian Morocco A Grade with COA

Description

**A-Grade Phacops Trilobite Fossil**

This genuine Phacops trilobite is an A-grade fossil from the Taboumakhlouf Formation at Tahrajat, Morocco. It dates from the Eifelian Stage of the Middle Devonian and represents an animal that lived in an ancient marine environment approximately 393 to 388 million years ago. The fossil has been carefully chosen for its quality, character and display appeal. The photographs show the exact specimen you will receive, allowing you to examine its preservation, matrix, preparation and natural colour before purchase. Please refer to the photographs for full sizing.

**Eifelian Geology of Tahrajat**

Tahrajat lies within the fossil-rich region of south-eastern Morocco, where extensive Devonian sedimentary rocks preserve a remarkable record of prehistoric marine life. During the Eifelian, this part of northern Gondwana was covered by a warm sea. Carbonate mud and other sediments accumulated on the seabed, burying the remains of trilobites together with brachiopods, cephalopods, corals and additional marine invertebrates.

The Taboumakhlouf Formation records episodes within this Devonian marine setting. Burial protected the mineralised dorsal exoskeleton of this trilobite from complete destruction. Compaction, chemical alteration and mineral replacement over millions of years transformed the remains into stone. Later geological uplift and erosion brought the fossil-bearing layers close to the surface, where specimens could be discovered and prepared.

**Classic Phacops Features**

Phacops belongs to the order Phacopida and family Phacopidae, a celebrated group of trilobites known for robust exoskeletons and highly specialised eyes. The body is divided lengthways into three lobes and crossways into the cephalon, articulated thorax and pygidium. This construction gave the living animal both protection and flexibility as it moved over or within the seabed.

One of the most distinctive phacopid features is the pair of prominent schizochroal compound eyes. These eyes were formed from comparatively large calcite lenses, each separated from the next, and provided a broad field of vision. The raised glabella occupies the centre of the cephalon, while the thoracic segments form a flexible armoured section behind it. Articulation allowed Phacops to enrol defensively, bringing the head and tail shields together to protect the softer underside from predators and disturbance.

The fossil therefore offers a direct view of an important evolutionary experiment in arthropod vision and defence. Its recognisable form makes it valuable for teaching about segmentation, exoskeletons, adaptation and the diversity of life in Devonian seas.

**Natural Fossil for Collection and Display**

This specimen is suitable for a fossil cabinet, geology collection, classroom resource or natural history display. Phacops trilobites are especially popular with collectors because their broad head shields, strongly defined body segments and conspicuous eyes create an immediately recognisable appearance. The Moroccan provenance also connects the piece with one of the world’s best-known sources of Devonian trilobites.

As a genuine fossil that has been excavated and prepared from rock, it may show natural matrix, mineral staining, small cracks, minor chips, preparation marks, stabilised or restored areas and variations in surface texture. These characteristics are normal for prepared trilobites and are part of the individual specimen’s geological and collecting history. The photographs document the actual piece supplied rather than a stock example.

**Certificate of Authenticity**

Your Phacops fossil includes a generic Certificate of Authenticity card with a lifetime guarantee. This confirms that the specimen is a genuine fossil and records its supplied geological age and provenance. The combination of authentic Eifelian age, classic Tahrajat locality, A-grade presentation and certification makes this trilobite an appealing acquisition for an established collector or a thoughtful gift for anyone interested in palaeontology, natural history and ancient marine ecosystems.
