This is a fabulous spiny trilobite. It is a large Long-Horned Kettneraspis from Morocco. This specimen was meticulously prepared under a microscope in the EXTINCTIONS Prep Lab here in Colorado, as are all of our Moroccan trilobites. The bug has great natural color and very fine detail preserved. The long pleural spines are intact, as are the fine fringes on the free cheeks. The stalked eyes and long occipital ''horn'' were all prepared free-standing. And the way the bug lays on the large, sculpted limestone plate is simply beautiful. This is a very collectible example of this ''showy'' Odontopleurid trilobite - extremely hard-to-find in this condition and presentation.
