4.9" Huge Phacopid (Drotops) Trilobite - Issoumour, Morocco
This is an exceptional, 4.9" long example of Drotops megalomanicus from Issoumour, Morocco. Preserved in a prone position, the specimen exhibits outstanding three-dimensional relief and a bold, sculptural presence on the matrix.
The compound eyes are especially impressive, retaining crisp preservation of numerous individual facets. Combined with the strong shell definition and substantial size, this is a visually striking example of one of Morocco’s most iconic Devonian trilobites.
Approximately 12–15% of the shell has been professionally restored.

About Drotops
Drotops is a genus of large Phacopid trilobite found in Morocco. The genus includes two species: Drotops megalomanicus, known for its smoother exoskeleton, and Drotops armatus, distinguished by its spiny armor. Renowned for their impressive size, these trilobites can reach lengths of up to seven inches, with most specimens ranging between four and five inches.
One of the most striking features of Drotops trilobites is their highly detailed schizochroal eyes, which contain dozens of individual facets. In well-preserved and expertly prepared specimens, these intricate eye structures are prominently visible, offering a glimpse into the advanced visual adaptations of these ancient arthropods.

How a Drotops might be found in the field, with part of the tail exposed in the broken rock. It would then be prepared using airscribes (or air pens) and air abrasives in a process that would likely take 20+ hours for a good specimen.
