Long-Spined Cyphaspides Moroccan TrilobiteDescription: Unusual example of a member of the Order Proetida, Family Aulacopleuridae with many fine details present. It comes from a new location known as Jorf in Morocco, close to the site from which the polished goniatite ammonites originate. The preservation of the exoskeleton is reminiscent of them in terms of texture, unlike many trilobites from Morocco. It has similarities to Cyphaspis (see my other listings) with the same bulbous cranidium, stalked eyes, and granulose appearance. It is a rarely-seen taxon, and most like this one are usually found somewhat disarticulated. The matrix from Jorf is often harder than that from some other sites, making preparation more difficult. The cranidium of this one is somewhat more vaulted in aspect than some I have seen before. I do not know if this is the result of intraspecific variantion or if this one is an entirely new species. With a burgeoning interest in specimens from Jorf, new material is being found much faster than it can be described. I include one inprep photo.
