Here is a pair of highly uncommon trilobites from Morocco. These are very attractive examples of Cornuproetus (Diademaproetus) antlatiasus from the Devonian. This specimen was microscopically prepared in the EXTINCTIONS Prep Lab here in Colorado. This type of trilobite has a distinct, subtriangular cephalic process and extremely long, flowing genal spines. These features are beautifully displayed on both of the trilobites. This inflated bugs are wonderfully articulated and extremely detailed. The large, bulbous glabellas are easily seen, and the protruding eyes are clearly defined. The trilobites have thick, black-shelled exoskeleton and contrast well with the light grey matrix plate. The bugs are nicely showcased on the sculpted block of limestone. This is a very displayable double specimen of this rare Proetid trilobite.
