Large Complete and Large Molt Elrathia kingii Fossil Trilobite | Wheeler Shale Formation, Delta Utah

This stunning Elrathia kingii trilobite is a remarkable fossil from the Middle Cambrian period, over 500 million years ago. Elrathia trilobites are well-known for their iconic, streamlined shape and well-defined body segments, making them one of the most recognizable trilobite species.

Trilobites like Elrathia kingii thrived in the warm, shallow seas that covered much of North America during the Cambrian period. As early arthropods, they were among the first creatures to develop complex eyes and a hard exoskeleton, both key features in their survival and evolution. The Cambrian is often referred to as the "Cambrian Explosion" because of the rapid diversification of life forms that occurred during this time.

Both specimens measure approximately 1.3" and 1.4" in length, while the surrounding matrix is 4.5" x 7.25" x 1", providing an ideal presentation of this ancient creature. Perfect for fossil collectors, educators, or anyone with a passion for prehistoric life.
