Emeraldella Like Burgess ShaleDescription: This unusual specimen has trilobitomorph features, and has as yet not been described in the Emeraldellaliterature. It is thought to have affinities with the Burgess Shale genus Emeraldella, but has a broader aspect than examples I have posted (see my other offerings). Notice that the pointed tail spine is present, a feature not always preserved with either the Trilobitomorphs or the Aglaspidids of the region. The most unusual component is the presence of much of the segmented antennae, a feature I have never seen on any of the specimens I have had to date. Any collector of Cambrian fossils from Utah would be pleased to add such an exceptional example.
