Here is an excellent specimen of Elrathia marjumi from the Marjum Formation of Utah. This species of Elrathia is much more rare than Elrathia kingi. It differs from the more common Elrathia kingi in having only twelve thoracic segments instead of thirteen. This outstretched trilobite is wonderfully articulated and exhibits outstanding detail. Both free cheeks are present, and even the small pygidium is intact. The crescent-shaped eyes are easily seen, and the individual thoracic segments are clearly defined. The bug has fine color and contrast and is well centered on the somewhat rectangular plate of shale. This is a textbook example of this unusual species of Elrathia from the Middle Cambrian.
