Elrathia kingii Trilobite

Travel back approximately 507 million years with this beautifully preserved Elrathia kingii trilobite fossil from the Middle Cambrian Period. Discovered in the famous Wheeler Shale of Utah's House Range, this specimen offers a fascinating glimpse into marine life that existed hundreds of millions of years before the dinosaurs.

Measuring approximately 1 inch, this trilobite features a rounded head shield, a distinctly segmented body, and a gently tapered tail shield. Its dark exoskeleton displays a raised central axis and finely defined thoracic segments, creating a striking contrast against the warm, golden-tan shale matrix. The surrounding stone features natural markings and subtle variations in color that add character to this attractive fossil.

Elrathia kingii is one of the most recognizable trilobite species from North America. These ancient marine arthropods inhabited the seas that covered present-day Utah during the Cambrian Period. Their hard, segmented exoskeletons helped protect their bodies while allowing flexibility and movement along the seafloor.

The Wheeler Shale is renowned for its exceptional Cambrian fossil preservation, particularly its abundant trilobites. With its classic trilobite anatomy, attractive natural coloration, and rich geological history, this Elrathia kingii specimen makes a wonderful addition to any fossil collection.
