Dramatic Tower-Eyed Erbenochile Trilobite With Barrandeops

This a rare, tower-eye, Erbenochile issoumourensis trilobite from Foum zeguid, Morocco. 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.
This dramatic specimen2" long it outstretched and is beautifully prepared. The huge compound eyes can be seen in all of their glory, the axial and tail spines are all free-standing. There is no restoration to the specimen, and there is an added bonus of an enrolled Barrandeops naturally associated with it.
