1.55" Bellacartwrightia Trilobite - New York

This is a 1.55" long Bellacartwrightia trilobite from the Windom Shale of New York. This is a fairly uncommon species to find complete and this one is above average size. There is about 5% shell restoration where some shell had flaked during collection.

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.
