Prone Metacanthina Trilobite - Healed Bite Mark #71615

This is a cute, little, 1.2" specimen of Metacanthina issoumourensis often referred to as an "Asteropyge" or “Kayserops”. It's has great preservation and preparation. There is a healed injury/bite mark on the left hand side of the tail which is quite interesting.

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.
