This very spinose Trilobite is a Ceratonurus, it is a type which is very recognisable for its spinosity. This prehistoric arthropod has numerous short spines which form a frill on the front leading edge of the librigenes (facial cheeks), The very long genal spines (Head shield spines), are widely spaced at either extremity of the cephalon (head shield) angled almost horizontally at an angle of around 75°. Two elegantly tapering backwardly curved spines emanate from the occipital ring, while long spines emanate from the 3rd, 4th and 5th pleura. The 5th pleura has the longest spines while the 6th come a close runner up the elongated and graceful pair of spines languish in inner space. The pygidium has many short spines. All these point towards a highly developed defensive or sensory system for the trilobite carapace.
A remarkable trilobite with a remarkable amount of defensive or sensory spines all extremely well exposed and in this specimen articulated in a very dramatic display. The preservation is excellent, the preparitors work a wonderful delight to behold. This is definitely one of our firm favourites and a recommended fossil trilobite specimen.
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.Follow this link to discover another world.
