.55" Bumastus Ioxus Trilobite - New York

This is a .55" long Bumastus ioxus trilobite from the Rochester Shale near Middleport, NY. It was collected from Caleb's Quarry.

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