This is an excellent spiny trilobite. It is a Dicranurus monstrosus from Morocco. This specimen is fully complete and is nicely outstretched. It has great color and very nice detail. The "ram's horns" are free-standing and stick well up off the back of the trilobite. All of the spines are natural and unrestored. The bug is preserved on a large block of matrix. This is a very collectible and displayable trilobite.
