Emeraldella is a rare arthropod of relatively large body size that belongs with the trilobite-like arthropods, Artiopoda. E. brutoni n. sp. from the Wheeler Formation of west-central Utah is the second species described and marks the first confirmed occurrence of Emeraldella outside the Burgess Shale of British Columbia. An articulated, flagelliform telson, similar to that of the Burgess Shale taxon Molaria, is recognized in Emeraldella. Evidence for the presence of lamellae on the exopods of Molaria is presented, supporting affinity of that taxon with Artiopoda. A close relationship between Emeraldella and Molaria is tentatively suggested, based on the morphology of tergites and telson.
