2.2" Phacopid (Adrisiops) Trilobite - Rock Removed Under Shell
This is a 2.2" long, phacopid (Adrisiops weugi) trilobite from Jbel Oudriss, Morocco. Adrisiops had been informally referred to as 'smiley Phacops' until it was described as the type species of a new genus in 2017. It is one of the less frequently seen genus of phacopids from Morocco.
The preparation on this specimen is incredible with most of the rock removed from underneath the shell. This allows light to shine through and the shell to become translucent when back lit.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
