1.6" Tower Eyed Erbenochile Trilobite With Three Morocops

This a beautiful, 1.6" long Erbenochile erbeni trilobite naturally associated with three Morocops. The preparation on the piece is fantastics with less than 1% shell restoration in total. The larger Moroccops has been prepared so that the hypostome on it's underside can be seen.

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 rounded triangular and without tubercles.
