Spiny Comura Trilobite

With its dramatic spiny projections, intricately segmented exoskeleton, and impressive three-dimensional preservation, this Comura sp. trilobite is a remarkable example of the extraordinary marine life that inhabited Earth's Middle Devonian seas.

Dating to the Middle Devonian Period approximately 390 million years ago, this specimen comes from the Tazoulait Formation in the Alruif region of Morocco. Comura trilobites are particularly recognized for their elaborate spines, distinctive body segmentation, and striking appearance. These fascinating marine arthropods inhabited ancient seafloors, where their prominent spines may have helped provide protection against predators.

This impressive specimen measures approximately 3 inches long and is preserved on a natural matrix measuring approximately 3.75 × 3.5 inches. Its dark exoskeleton contrasts beautifully with the textured gray matrix, highlighting its numerous elongated spines, raised central axis, and intricate anatomical details. The detailed preparation showcases its dramatic three-dimensional form, with spines extending outward along both sides of the body and prominent projections rising from the exoskeleton. Its striking appearance makes it an exceptional display specimen from Morocco's rich Devonian fossil record.

A Certificate of Authenticity from Tyrannostorus is included.
