Bargain, 1.6" Spiny Comura Trilobite - Oufaten, Morocco

Bargain, Spiny Comura Trilobite - Oufaten, Morocco #160892

This is a 1.6" long Comura bultyncki trilobite from Oufaten, Morocco. It's fairly small for the species and the preparation work is just ok, hence the bargain price.

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.
