Here is a very fine example of a highly collectible trilobite. This is Aristoharpes sp. from the Devonian of Morocco. Harpid trilobites are among the most sought-after trilobites 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. These long, wide genal spines have been meticulouly prepared in a free-standing manner on this specimen. The thorax is composed of many, many segments and the pygidium is almost miniscule in comparison. This large example is nicely outstretched which is highly unusual - usually these trilobites are found with the tail tucked underneath, if present at all. It is preserved in a very 3-dimensional fashion and exhibits fine detail. The small eyes are easily seen and the granulose ornamentation of the brim is beautifully defined. The thorax is well articulated and even the pygiium is intact. The dark trilobite contrasts wonderfully with the light-colored matrix. It is nicely presented on the plate of limestone. With the genal spines extending into the air like "wings", this is a very displayable specimen of this unusual trilobite.
