Here is a very nice example of Elrathia marjumi from the Marjum Formation of Utah. We recently acquired this specimen from the DeRosear Collection. This species of Elrathia differs from the more common Elrathia kingi in having only twelve thoracic segments instead of thirteen. This trilobite is wonderfully articulated and exhibits fine detail. Both free cheeks are intact and tightly attached. The short genal spines are easily seen, and even the tiny pygidium is present. The bug has oustanding natural color and contrasts beautifully with the lighter-colored matrix. It is well presented on a somewhat rectangular plate of shale. This is an excellent specimen of this unusual species of Elrathia from the Middle Cambrian.
