This is a strange US trilobite. It is an excellent Menomonia semele from the Upper Cambrian of Utah. This specimen is not only complete, it is quite symmetrical. The free cheeks are intact, and the large, stalked eyes are very easily seen. The thick shell exoskeleton is finely detailed and exquisitely preserved. The rich, dark brown bug contrasts beautifully with the natural red matrix. This is a very fine example of this multi-segmented trilobite from Utah.
Note: This specimen was obtained legally. However, normally it is illegal to sell fossils from the Weeks Formation and other BLM lands.
