This is a classic U.S. trilobite. It is a complete 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 is very prone and exhibits fine detail. 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 entire carapace of the trilobite is covered with distinct pustules. The fossil has great color and contrast and is nicely showcased on the squared matrix plate. This is a great example of this highly collectible Lichid trilobite.
