1.35" Rare Apatokephalus Trilobite With Two Lonchodomas

Rare Apatokephalus Trilobite With Two Lonchodomas #255442

This is a rare, 1.35" long Apatokephalus trilobite from the upper Fezouata Formation of Morocco. This rare remopleurid trilobite has a long spine coming off the axial ring on one of its last segments. The red/rust coloration is natural and due to the oxidization of iron pyrite. It is associated with a pair of Lonchodomas. Total restoration is only about 1%

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.
