Hollardops mesocristatus

Hollardops mesocristatus (formerly known as Metacanthina) is a magnificent trilobite from the Middle Devonian. Hollardops lived on the ocean floor, which is now part of the Atlas Mountains of Morocco. Hollardops is renowned for its big semi-circular eyes containing multiple schizochroal eye lenses.

The trilobite is 2.66 inches long and 1.55 inches wide. Trilobite and matrix is 3.88 by 3.22 by 1.44 inches. The schizochroal lenses in both eyes are extremely well-preserved.

There is a repair running diagonally across the thorax and exiting the base of the right genal spine, and another through the keft aye and around into the thorax.
