This is a beautiful 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 both genal spines and occipital spine ''Ram's Horns'' are prepared in a free-standing manner. The body spines are very long and flow beautifully. The bug has great color and contrast and is wonderfully showcased on the large, sculpted block of limestone. This is a fabulous display example of one of the most recognizable trilobites among collectors.
