2.45" Asaphus Lepidurus Trilobite - Gorgeous Specimen

This is a beautiful, 2.45" 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. This is a top quality specimen of the species. There is only about 3-4% shell restoration, on the top of the axis and outer edge of the tail.

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.
