Bug-Eyed Coltraenia (Treveropyge) Moroccan Trilobite

Description: Elegant example of a member of the Order Phacopida, Superfamily Acastoidea with many fine details present. While most frequently known in the trade as "Treveropyge", this one is actually Coltraenia. The most diagnostic features of this taxon are the high "eye-towers". Notice the many exceptional eye facets present on this specimen. The "wrap around" eyes gave a good panoramic view of the trilobite's environment, allowing it to keep alert for predator and prey alike. Since fish had recently evolved true jaws, any advantage a prey species could derive would place it at an advantage.
