Rare Species Ceratarges aries Moroccan Trilobite

Description: The spiny trilobite is a member of the Order Lichida, Family Lichidae from the Devonian deposits of Ofaten, Morocco known as a member of the genus Ceratarges. This one more likely Ceratarges aries which was assigned a species name a few years ago the source of which is derived from the fact that the spines of the head are reminiscent of a ram.. It is the rarest of the three newly-described Ceratarges. Indeed, it only represented some 5 percent of the specimens found at the type locality. The dramatic cephalic spines have been prepared freestanding. It is an excellent example of the taxon with numerous bizarre features. Even the hypostome is preserved. See my other offerings for yet other members of the genus, Ceratarges ziregensis and Ceratrges koumalii.
