This is a very detailed example of a classic U.S. trilobite. It is a large Arctinurus boltoni from the Silurian of New York. This is one of the most sought-after and displayable types of trilobites in the world. We collected the quarry for a year, and only found a handful of complete specimens. This wonderfully articulated trilobite exhibits extrmely fine detail - the entire carapace of the trilobite is just covered with distinct pustules. The trilobite is extremely inflated, and the cephalic process (''snout'') is easily seen. The pleural spines terminate in sharp points, and the broad, fan-shaped pygidium is beautifully displayed. The bug has great color and contrast and is nicely showcased on the natural matrix plate. And at almost six inches long, this is one of the larger Arctunurus ever found. This is a large, top quality example of this highly collectible Lichid trilobite.

A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
