Emeraldella

Extinct genus of arthropods

Extinct genus of arthropods

Description

Taxonomy

In 1923, Emeraldella was placed, along with Sidneyia, as part of the group "Xenopoda". Today, both Sidneyia and Emeraldella are placed as part of the clade Vicissicaudata within Artiopoda, which includes trilobites and other arthropods with similar bodyforms. However, Sidneyia and Emeraldella are usually not recovered as each others closest relatives within Vicissicaudata, rendering "Xenopoda" invalid.
