Elrathia, Bolaspidella And Peronopsis Trilobites

This is a cool association plate with three different types of trilobites present from the famous U-Dig quarry of Utah. There is a complete Elrathia kingii (1/2 inches), a large Elrathia missing it's tail, at least 8 small Peronopsis interstrictus (agnostid trilobites) and two small Bolaspidella housensis trilobites. Even from the quarry with it's prolific trilobite fauna, it's unusual to get 3 different species complete on a single plate.
