This particular spiny variety of trilobite is a Ceratonurus, it is most definitely recognisable by its spinosity. This individual has numerous short spines forming a frill on the front leading edge of the librigenes (facial cheeks), with very long genal spines (Head shield spines), which are angled almost horizontally at an angle of around 75° from the cephalon (head). Two elegantly tapering backward curving spines 'resembling horns' erupt from the occipital ring, while long spines emanate from the 3rd, 4th and 5th pleura (segments - furrows of the carapace). The 6th pleura has the longest spines. The pygidium (tail), has many short spines and a posterior frill of even smaller short spines. All these spines indicate a defensive system for the trilobite.
A remarkable trilobite with a remarkable amount of defensive spines all well exposed and in this specimen articulated in a very dramatic display. The preservation is excellent and the preparitors work an amazing delight to behold. Definitely a recommended example and another of our firm favourites.
The reddish brown colour of the matrix denotes the red layer location. Our team of Moroccan fossil technicians have excavated the raw rock and have with specialist technical process's using pneumatic power tools ground the limestone away from the specimen trilobite revealing the fine and extremely delicate spines. This first hand knowledge is valuable to our team, the fossil has travelled directly from the fossil location to our store, a unique product delivery.
