2.4" Tower Eyed Erbenochile Trilobite - Spectacular Specimen!

This an absolutely stunning specimen, rare, tower-eye, Erbenochile erbeni trilobite from Foum Zguid, Morocco. It's good-sized and would have been about 2.4" long if outstretched. The quality of preparation on this specimen is insane! Just check out the eye facet detail and tiny spines. I'm guessing that around 100 hours of work under microscope went into this beauty.

This species has extraordinarily large eyes containing over 400 eye facets. The massive eyes allow full 360 degree coverage in the horizontal plane and were high enough to allow the trilobite to see backwards over its thorax.

There are two known species of Erbenochile and Erbenochile issoumourensis is distinguished from Erbenochile erbeni by several key features. Issoumourensis has a smaller number of eye facets, it does not have an "eye shade" extending laterally from the to of it's eyes, the spines of shorter, and the cephalon rounded triangular and without tubercles.
