Elrathia kingii is a species of trilobite that lived during the Middle Cambrian period, approximately 505 million years ago. It is a common fossil found in the Wheeler Shale Formation of Utah, which is known for its well-preserved fossils of a variety of Cambrian marine animals.

Elrathia kingii is a small trilobite, typically measuring between 2 and 5 centimeters in length. It had a distinctive oval-shaped body with a prominent head and tail, and a series of segments along its body that were divided into three lobes (hence the name "trilobite").

The Wheeler Shale Formation is located in central Utah and is part of the larger Basin and Range Province of the western United States. The formation was deposited in a shallow sea that covered much of western North America during the Cambrian period, and it contains a rich fossil record of the diverse marine life that lived during this time.
