Bargain, 1.1" Paciphacops Trilobite - Oklahoma
This is a detailed and nicely prepared Kainops raymondi trilobite from the Haragan Formation of Oklahoma. It has been painstakingly prepared under microscope using air abrasives. The caramel colored shell contrasts nicely with the creme colored rock. There is missing shell a pleural tip on the right side and slight disarticulation between the head and body, hence the bargain price.

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