1.9" Tower Eyed Erbenochile Trilobite

This is a dramatic tower-eyed Erbenochile trilobite from Foum Zguid, Morocco. This specimen has a backwards arch to it and would be about 1.9" long if outstretched. Clear eye facets in both eyes and dozens of free standing spines. There is about 5% shell restoration on this specimen, along repaired cracks, very top of the right eye and the right lower corner of the tail.

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 top of its eyes, the spines are shorter, and the cephalon is rounded and triangular and without tubercles.
