2.15" Tower Eyed Erbenochile Trilobite - Foum Zguid, Morocco

This a 2.15" long, tower-eye, Erbenochile erbeni trilobite from Foum Zguid, Morocco. Excellent preparation with dozens of free-standing spines and clear eye facets. The tail on this specimen is likely a composite and there is about 6-8% shell restoration, at the end of the tail and along repaired cracks.

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.
