This is an unusual Silurian fossil. It is a Calymene and Maurotarion double from Indiana. The plate has a large Calymene breviceps and a Maurotarion christyi cephalon nicely spaced on the matrix. Both specimens are natural - no compositing. The Calymene has both free cheeks, and so does the Maurotarion. There is no restoration to either bug. This is a rare natural double of Silurian trilobites.
