2" Top Quality Tower Eyed Erbenochile Trilobite

 
 
 
 
This an absolutely stunning specimen, rare, tower-eye, Erbenochile issoumourensis trilobite from Foum Zeguid, Morocco. It's preserved in a "climbing" position but would be about 2" long if outstretched. Excellent preservation with no major restoration.

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.
