Cluster Of Four Symphysurus Trilobites - Preserved Antennae!

This is an impressive, 11.5" wide cluster of Symphysurus trilobites from the Fezouata Formation of Morocco. They are quite large for the species and two of them have rare preservation of antennae!

The Fezouata Formation is known for occasionally yielding soft-bodied preservation including trilobite appendages. The trilobites were buried in an anaerobic (free of oxygen) environment allowing for fossilization of soft parts before they decomposed. The shell of the trilobites was originally preserved as pyrite which has since oxidized to a red-orange coloration.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
