2" Adrisiops Weugi Trilobite - Excellent Preparation

This is a 2" long (if outstretched), outstretched specimen of Adrisiops weugi, a fairly new species of phacopid from Morocco. It has a distinctive bulging glabella covered in large tubercles.

We have previously incorrectly labeled some specimens of this species as Phacops araw. Superficially the two species look very similar, but Phacops araw has fewer eye facets than Adrisiops weugi.

The paper on this species can be found below.

The phacopine trilobite genera Morocops Basse, 2006 and Adrisiops gen. Nov. from the Devonian of Morocco

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.
