Acanthopyge consanguinea Oklahoma TrilobiteDescription: This is an extremely rare trilobite of the Order Lichida, affectionately referred to as “Bug X” by its discoverer, the master preparator Bob Carroll of Clarita, Oklahoma. It is most likely the same as Acanthopyge consanguinea first described from New York. First discovered in 1999, Bob has found only a few dozen. This one is even rarer in that the hypostome has been preserved in association. Other than a single ventrally-prepared specimen, and one isolated example, this is only the third one known. Given that it is almost the same size as the cranidium, it is indicative of a predatory lifestyle. Bob is well-known throughout the collecting community for the exceptional quality of his work. Here is a unique opportunity to not only obtain a trilobite prepared by Bob, but also one discovered by him as well. It is rendered even more desirable in having the hypostome in association, a fact verified by me in personal communication with Bob.
