1.5" Stunning Erbenochile Trilobite with Hollardops - No Restoration!
This is a stunning specimen of the tower-eyed trilobite Erbenochile from the Timrhanrhart Formation of Morocco. It measures 1.5" long and much of the limestone has been removed from the lateral spines. Even a tiny trilobite pygidium has been exposed and left attached to the pygidium of the Hollardops. Exceptional detail and preparation on this specimen. Just check out the facets in the tower eyes and all of its tiny spines.
Naturally associated with the Erbenochile is a 1.4" long (if outstretched) Hollardops. Both are entirely free of restoration. A truly outstanding multiple trilobite specimen!
Erbenochile 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, with E. issoumourensis being distinguished from E. erbeni by several key features. E. 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.

About Trilobites
Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
