Reedops maurulus is an Early Devonian trilobite from Morocco, part of the Phacopid clade. Specimens typically range from 3 to 6 cm in length. Fossils are found in Pragian-age marine limestones, often well-preserved and enrolled. This species lived as a benthic predator or scavenger on shallow seafloors.

It’s often confused with similar species but can be reliably identified by its smooth, spineless pygidium with shallow furrows and no ornamentation. The glabella is moderately elongated, and the occipital furrow is distinct, extending to the genal field. Its exoskeleton shows fine granulation without pustules, and the large compound eyes are typical of phacopids. If the pygidium is smooth and unarmed, you’re likely looking at R. maurulus—just confirm with the glabella and furrow shape.
