Killer 1.3 Inch Long Orygmaspis Contracta

This is an absolutely killer specimen of an Upper Cambrian trilobite that is seldom seen for sale, Orygmaspis contracta. This detailed trilobite has long genal spines running about half the length of the body, a pair of extended pleural spines and four pairs of tiny spines on it's pygidium. This one is 1.3 inches long and preserved about as good as they get. Due to the soft shale matrix and the thinness of the shell, specimens rarely are preserved this nice, often missing substantial portions of their shell.

This is part of a small selection of trilobites from this location which I was able to obtain in a trade.
