As everyone knows, complete Mississippian trilobites are quite rare. This is a large Comptonaspis swallowi from the Mississippian of Missouri. This genus of trilobite has a very smooth carapace - almost totally devoid of any ornamentation. This type of trilobite is found in the same formation as Breviphillipsia sampsoni, but Comptonaspis is about ten times more rare. This specimen is extremely large for the type and very well articulated. The bug is nicely inflated, and the eyes are easily seen. The dark brown color of the trilobite contrasts wonderfully with the light-colored matrix. The trilobite is well presented on the natural limestone plate. This is a fine example of this highly uncommon trilobite from the Mississippian.
