Fossil Site: Haragan Formation, Coal County, Oklahoma

Description: 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 has reecently been determined by Dr Bruce Lieberman, Associate Professor of Geology of the University of Kansas to be Acathopyge consanguinea, a taxon originally described from a partial speciemen found in New York. It has affinities with the Moroccan genus Lobopyge (see my Moroccan trilobites for an example). In the 18 years he has operated a quarry located on what is called Black Cat Mountain, Bob has only found some 30 examples of this rare trilobite. Bob numbers each one; this one is Number 29 from the quarry, and comes from the south section (see the photo of the reverse). Bob is well-known throughout the collecting community for the exceptional quality of his work.
