Wonderful Acanthopyge (Lobopyge) Trilobite

This is a fine specimen of a rare lichid trilobite, Acanthopyge (Lobopyge) bassei from Atchana, Morocco. At 1" long if outstretched it's large for the species, and it's preserved in a posture this species is nearly always found in, arched backwards. The preparation on this specimen is very nice, notice all the minute shell details that were preserved. No restoration.
