Bruer, field assistant, were on a geological expedition near Mount Skinner while working for Kennecott Explorations, Pty.

Halliday and Bruer notified Mary Wade of the Department of Geology at the University of Adelaide.

Wade (1969) described Skinnera as a medusa,[2] though, other sources classify it as a trilobozoan related to Tribrachidium and Hallidaya.
