This is a very impressive example of a classic U.S. trilobite. It is a textbook 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 fabulous trilobite was acquired from the elite collection of the late Eugene Thomas - one of the most respected trilobite collectors in the world. This wonderfully articulated trilobite exhibits very fine detail - the entire carapace of the trilobite is covered with distinct pustules, and the thick shell exoskeleton is quite dark and shiny. The extremely large trilobite (almost SIX INCHES LONG! ) is quite 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 displays beautifully on the squared block of thick shale. This is a very large, very detailed example of this highly collectible, classic Lichid trilobite direct from the Eugene Thomas Collection.

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