Dicranurus monstrosus
Trilobites Order: Lichida, Family: Odontopleuridae
Geological Time: Lower Devonian
Size: 2.2 inches
Fossil Site: Lower Devonian Laatchana Formation deposits near Alnif, Morocco
Here is one of the more sought after trilobites of the Order Lichida, Family Odontopleuridae known as Dicranurus monstrosus. This particular example is quite large at 2.2 inches in length from the dramatic cephalon to the wonderful pleural spines, and has a "wingspan" of 2.6 inches at the genal spines. Notice that the librigenae are tightly attached, a sign of a well-articulated specimen. It is found in the Lower Devonian Laatchana Formation deposits near Alnif, Morocco. It is quite prone, and dominates its 2.7 inch by 2.9 inch bed of matrix. Among its impressive features are the dramatically retorted occipital spines, looking like ram's horns. In all, there are 18 freestanding spines present, making for an impressive display piece. To what purpose could this spiny exoskeleton have been evolved? The answer is simple -- DEFENSE!! Fish had recently evolved jaws, and in the never ending arms race between predator and prey, Dicranurus' amswer was a spectacular defensive array of spines. A substantial amount of prep time goes into a dramatic specimen such as this.
