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.
