Small Elrathia Trilobite Multiple - Utah

Here is a 505 million year old trilobite fossil from the Wheeler Shale of Utah. This fine specimen has been cleaned with air abrasives under microscope which while more time consuming, yields superior detail to how the quarries clean most of these trilobites.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
