Uncommonly Preserved Modocia laevinucha
Here is a great example of Modocia laevinucha from the Marjum Formation of Utah. While it is a relatively common trilobite, they are rarely found with cheeks attach or a solid shell. This one was personally collected and prepared from a private lease in the House Range of Utah. You'll have a hard time finding another one this nice at any price.
