This is a large, detailed, 5.8"Drotops trilobite quarried from Issoumour, Morocco. It's good size for this large phacopid species and has excellent shell detail including beautiful eye facet preservation. The limestone has been removed from around it leaving it flying above the base of rock on a pedastal. It has a multi-toned coloration due to some of the shell being weathered but there is no restoration.

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 and air abrasives a process that would likely take 20+ hours for a good specimen..
