Koneprusia brutoni and Cornuproetus cornutusDescription: A fine pair of Devonian trilobites that care eye-catching from any aspect. The spiny example is a member of the genus Koneprusia, an elegant example of an unusual trilobite which as an Odontopleurid has many fine relatives in Dicranurus, Leonaspis, and Ceratonurus. This one has a plethora of spines, all of which have been painstakingly prepared freestanding. 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. a. The other trilobite is Cornuproetus ccornutus. The most diagnostic features of this taxon are granulose cephalon and thorax and the swept-back genal spines. The Proetidae were among the last of the trilobites to go extinct in the Permian over 100 million years later. This pair of trilobites of diverse morphology would make a fine addition to any trilobite collection.
