Crotacephalus gibbus Trilobite Fossil

With its distinctive elongated body, prominent spines, and beautifully defined exoskeleton, this Crotacephalus gibbus trilobite is a striking example of the remarkable diversity of marine life that inhabited ancient Devonian seas.

Dating to the Middle Devonian Period approximately 390 million years ago, this specimen comes from Hamar Laghdad near Erfoud, Morocco. Crotacephalus gibbus trilobites are particularly recognized for their elongated, segmented bodies and prominent projections extending from the sides of their exoskeletons. These fascinating marine arthropods lived along ancient seafloors, where their protective exoskeletons helped shield them from predators.

This specimen measures approximately 3 inches long and is preserved on a natural matrix measuring approximately 3.5 × 1.5 inches. Its dark exoskeleton contrasts beautifully with the light-colored matrix, highlighting the intricate body segmentation, pronounced spines, and impressive three-dimensional preservation. The detailed preparation showcases the trilobite's distinctive anatomy from multiple angles, making it an attractive display specimen from Morocco's rich fossil record.

A Certificate of Authenticity from Tyrannostorus is included.
