Molaria
''Molaria spinifera'' is a species of chelicerate-like arthropod known from the Middle Cambrian Burgess Shale. The body of ''Molaria'' consisted of a head shield (cephalon), a trunk consisting of eight sections (tergites), and a telson, which included a short ventral spine and a long posterior spine. Three pairs of legs were beneath the cephalon and another eight pair were attached to the trunk. Eyes were lacking, but a pair of short antennae was present on the cephalon. Specimens of ''Molaria'' ranged from 8 to 26 mm in length from cephalon to telson, with the posterior spine slightly longer than the body length. ''Molaria'' was superficially similar to ''Habelia'', another Burgess Shale arthropod with a long tail spine, but which possessed 12 trunk tergites.〔 The genus name derives from "Molar", the name of a mountain peak east of the Valley of the Ten Peaks in Alberta, Canada.〔 == References ==
