This is a classic Cambrian trilobite. It is a very fine Acadoparadoxides nobilis from the Cambrian of Morocco. This specimen was meticulously prepared under a microscope in the EXTINCTIONS Prep Lab here in Colorado. This unusual species of trilobite is complete and wonderfully articulated. Both free cheeks are present, which is EXTREMELY unusual for this type of trilobite. The inflated trilobite exhibits wonderful detail - the long, sweeping genal spines are intact and beautifully displayed. The crescent-shaped eyes are easily seen, and the pleural spines and tail are clearly defined. The trilobite has striking natural color and is well displayed on the rounded plate of matrix. This is a fabulous, complete specimen of this classic Cambrian trilobite - extremely rare in this ultra fine condition.
