Coltraenia (Treveropyge) Moroccan Trilobite
Order Phacopida, Superfamily Acastoidea - Formerly called Treveropyge
Time: Middle Devonian
Oufaten, Alnif, Morocco
Elegant example of a member of the Order Phacopida, Superfamily
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.
