    More than different trilobite species have been found across Utah, in a broken band of Cambrian Period ( to million years old) limestones, siltstones, and shales that trends northeast-southwest across the western part of the state. During the Early Cambrian (about to million years ago), western Utah was covered by a shallow sea. Specimens from the Wheeler and Marjum Formations of Utah comprising an elongate stipe with freely projecting conical thecae are described as dithecoid graptolites, the first reported from these units. The Wheeler Shale specimens, assigned to Archaeolafoea monegettae (Chapman, ), provide the first record of Archaeolafoea Chapman, from the Cambrian of Laurentia and show clear fusellar Cited by: 6.

Emeraldella is a rare arthropod of relatively large body size that belongs with the trilobite-like arthropods, Artiopoda. brutoni n. 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.

Since then, megacheirans have generally been considered precursors either to chelicerates, or to a group containing all living arthropods. A new metazoan, Skeemella clavula gen. et sp. nov., is described from the Middle Cambrian Pierson Cove Formation of the Drum Mountains, Utah, USA.

Skeemella is similar to vetulicolians, but differs from other examples of this group in the relative proportions of the anterior and posterior sections, the large number of divisions, and the elongate bifid termination.

The posterior section is. The Paleontological Institute is delighted to announce the immediate availability of these new publications: Martin, Stephen B. Church, & Richard A. Robison. A new Cambrian arthropod, Emeraldella brutoni, from Utah. Paleontological Contributions –9, fig.

The type species E. brocki was described in from the Burgess Shale. 21 specimens of Emeraldella are known from the Greater Phyllopod bed, where they comprise brutoni is known from the Wheeler Shale, which was Kingdom: Animalia.

Arthropods. In terms of numbers of species, the Phylum Arthropoda is the most diverse group of animals alive today, and was also the most diverse Cambrian group.

Examples of familiar arthropods include insects, millipedes and centipedes, spiders, horseshoe crabs, scorpions, shrimps, and crabs. THE earliest-known fully terrestrial animals are myriapods from the Upper Silurian of Britain1, and unnamed myriapod-like fossils have recently been.
