Happy Elrathia Kingii Day!!! It may not be a real holiday, but damn it, it should be. Or at least a cuss word.

Collected in 2015 at the House Range in Utah, close to Wheeler Quarry. While fairly common, these 505-Million-Year-Old Trilobites are extremely well-defined and a must-have for any collector.

Name: Elrathia kingii: The name Elrathia is based off the town Elrath in Alabama where these trilobites were discovered.
