2.25" Cambrian Trilobite (Acadoparadoxides) - Tinjdad, Morocco

Cambrian Trilobite (Acadoparadoxides) - Tinjdad, Morocco #198731

This is an excellent 2.25" long Acadoparadoxides trilobite from the Jbel Wawrmast Formation of Morocco. It's hard to get specimens as nice as this one. It is nicely presented on a large section of shale that has a second, partial, ventral specimen.

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.
