Description: Coming from the Cambrian Wheeler Shale deposits of Millard County, Utah this is a fine example of a trilobite assemblage. What is most unusual about this specimen is the fact that the Elrathia are the SMALLEST examples I have ever had. There are quite a few spread around the plate in association with a pair of Bolaspidella and three Peronopsis agnostid trilobites, making for an exceptional nursery piece.
