I found the rear section of a Devonian trilobite the other day. It was different than ones I have found before in that the center line or axial lobe was arched up like the roof of a house. These seems to match with a
Trypaulites trilobite.

Since the piece is turned over I mold its shape with some Crayola modeling clay.
