NEW UPPER CAMBRIAN TRILOBITES FROM THE CHOPKO RIVER SECTION

Abstract

Six new genera, one new subgenus, and ten new species of trilobites are described from the Upper Cambrian Chopko Formation from a section of the Chopko River, Norilsk District, northwestern part of the Siberian Platform. These include one genus and two species of agnostids and five genera, one subgenus, and eight species of polymerids. The new taxa come from an interval of the section attributed to the upper two-thirds of the Upper Cambrian. © Pleiades Publishing, Inc. 2006.
