Here is an excellent example of a highly collectible trilobite. This is Harpes perradiatus from the Devonian of Morocco. This specimen was painstakingly prepared under a microscope in the EXTINCTIONS Prep Lab here in Colorado. Harpid trilobites are among the most sought-after trilobites among collectors because of their rarity and bizarre design. This type of trilobite has a huge cephalon with a wide brim that extends into broad, sweeping genal spines, which were prepared free-standing on this specimen. The thorax is composed of many, many segments, and the pygidium is almost miniscule in comparison. This large specimen is nicely outstretched, which is highly unusual. The bug is preserved in a very 3-dimensional fashion and exhibits great detail. The small eyes are easily seen, the granulose ornamentation of the brim is beautifully defined, and the thorax is tightly articulated. The natural color of the trilobite contrasts nicely with the lighter-colored matrix. The fossil is well centered on the natural-edged block of sculpted limestone. This is a very collectible specimen of Harpes perradiatus, prepared in-house here at EXTINCTIONS.
