This is an absolutely stunning, 1.85" long example of the rare, tower-eye Erbenochile erbeni trilobite from Foum Zguid, Morocco. The preparation is truly top-tier, showcasing flawless, fully preserved eye facets in both eyes and dozens of delicate, free-standing spines.
Trilobites of the genus Erbenochile are among the most visually striking arthropods of the Devonian, famed for their extraordinary compound eyes. Each eye tower is composed of more than 400 individual facets, forming a sweeping dome that granted the animal an unmatched field of view. These massive optical structures provided full 360° horizontal coverage, and were tall enough to allow the trilobite to peer backward over its own thorax—a remarkable evolutionary advantage in the predator-rich seafloor ecosystems of the time.
