2.4" Large Metacanthina Trilobite - Top Quality Specimen

Large Metacanthina Trilobite - Top Quality Specimen #209656

This is a top quality, 2.4" long specimen of Metacanthina issoumourensis from Lghaft, Morocco. I think this is pretty much maximum size for the species and the preparation is top notch. There is less than 1% restoration on top of a couple of axial rings.

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.
