5.3" Prone Drotops Trilobite - Issoumour, Morocco

This is a 5.3" long specimen of the large phacopid trilobite Drotops megalomanicus. The facets in the right eye are nice and clear, though there is a bit of damage to the left eye. About 3% shell restoration in total, primarily along repaired cracks.

One of the most striking features of this trilobites is the large schizochroal (multi-faceted) eyes which would have given it a nearly 360 degree field of vision. It also has a very bumpy exoskeleton, in particularly on it's head.

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..
