3.1" Asaphus Lepidurus Trilobite - Large & Top Quality

This is a beautiful, 3.1" long Asaphus lepidurus trilobite. It was collected from the Putilovo quarry in the St. Petersburg region of Russia. The caramel colored shell contrasts nicely with the light colored limestone. At over 3" long this is pretty large for the species. The tail on this specimen appears to be a composite, but otherwise there is no restoration.

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.
