This is a Koneprusia dahmani tribolite with spectacular thorns, extracted from the deposits of the Lower Devonian in Morocco. It differs from the more common Koneprusia brutoni by having a pair of spines detaching from the first two axial rings as opposed to a single spine.
Preparing a trilobite like this requires dozens of hours of highly skilled work to remove hard limestone from the surroundings layer by layer using airbrush and air abrasives, usually under high magnification. This specimen is very well prepared. Top quality.
