Description: Elegant example of an unusual trilobite which as an Odontopleurid that has many fine relatives in Dicranurus, Leonaspis, and Ceratonurus. This one has a plethora of spines, many of which have been painstakingly prepared freestanding, making for a spectacular display piece. To what purpose could such a spiny armament be put? The answer DEFENSE cries out; with fish only recently (geologically speaking) having developed true jaws, any advantage a prey species could evolve would stand it in good stead in the eternal predator/prey arms race. This one was the “Porcupine of the Devonian” with long spines projecting in all directions. The spines are all natural. Many of you may be aware that Moroccan preparators often remove spines during the process of exposing the specimen to access portions obstructed. They are subsequently reattached once the specimen has been fully exposed. I have included a pair of in-preparation photos so you can see the process. Since this type was first found some 15 years ago I know of only THREE other examples of this unusual variant.
