Two Symphysurus Trilobites - One Antenna Present

This is a pair of 1.8" long Symphysurus trilobites from the Fezouata Formation of Morocco. They have a natural purple coloration caused by the oxidization of iron pyrite which originally preserved the fossil. One trilobite has a single antenna preserved, a rare example of soft-bodied preservation of trilobite appendages.

It comes with an acrylic display stand.

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.
