Large Elrathia kingii Wheeler Trilobite

Description: Coming from the Cambrian Wheeler Formation deposits of Millard County Utah this is a detailed example of the trilobite Elrathia kingii. These trilobites are often found with disarticulated or missing free cheeks. This fine example is well-articulated, with a dark black exoskeleton which contrasts well with the beige shale matrix which derives its color from its high organic content. This is a large example, rarely seen in such a fine state, with both genals tightly attached.
