Triarthrus eatoni
Vendor: Gold Bugs
SKU Number: SQ1147447
Triarthrus eatoni from the famous Beecher’s Trilobite Bed, Upper Ordovician, Frankfort Shale, Lewis County, New York.
A large 2.8cm dorsal Triarthrus eatoni with excellent antennae and appendages. Large dorsals are hard to find with this level of preservation. This specimen is unique and noteworthy due to the number of very well preserved claw tips on the walking legs. These triple-pronged or tripartite claws are the way trilobites moved and anchored themselves in the substrate. These are rarely preserved and often in closed position, obscuring their wide range of opening. Note also the excellent preservation levels on the segments of the legs, many with sharp, spine-like setae outgrowths from the segments, similar to modern arthropods. The swimming appendages are also well preserved showing the hair-like gill features and the rounded, paddle-like tips. Outstanding specimen!

Additional Information
Discovered in 1892 by William S. Valiant and made famous by the work of Charles Emerson Beecher, "Beecher's Trilobite Bed" is located in a small quarry outside of Rome, New York. It is a 4cm thick layer of shale that has yielded some of the most spectacular fossils ever found. The most revered is Triarthrus eatoni, an Upper Ordovician trilobite from the Frankfort Shale of the Lorraine Group. The trilobite bed is a Konservat-Lagerstätte with exceptional soft tissue preservation of antennae, appendages and occasionally egg broods preserved near the underside of the cephalon. There exist only a few sites around the world that preserve this level of detail.
For the last 15+ years the quarry has been owned and managed by Markus Martin, founder of Gold Bugs. Not only is Markus the owner of Gold Bugs, he is the recognized expert on the preparation of fossils from this site.
