4.7" Arctinurus Trilobite - Class New York Trilobite

 
Here is a classic North American fossil and one most desirable trilobites. This elegant and large lichid comes from the famous "Caleb Quarry" near Middleport, NY. It's 4.7" long and nicely centered on a thick slab of shale. Only a small amount of restoration to the edges of a few tail spines.

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.
