This is an extremely spiny trilobite. It is a large Dicranurus monstrosus from the Devonian of Morocco. This specimen was meticulously prepared under a microscope in the EXTINCTIONS Prep Lab here in Colorado, as are all of our Moroccan trilobites. This type of trilobite is well-known for its spider-like appearance. This specimen is complete and very 3-dimensional. The bug is well articulated and exhibits fine detail. The free cheeks are intact, and the occipital spine ''Ram's Horns'' are quite large and prepared in a free-standing manner. The body spines are very long and were also prepared free-standing. The bug has great natural color and contrast and is wonderfully showcased on the sculpted block of limestone. This is a fabulous display example of one of the more favorite trilobites among collectors.
