Article: Lower Permian Bryozoa from Western Australia

Scattered bryozoan localities in the Lyons Group contain three species of Stenopora, S. dickinsi sp. nov., S. fisheri sp. nov., and S. lyndoni sp. nov., that show little similarity to previously described species. The fenestellid Polypora lyndoni occurring at all the bryozoan localities studied has close affinities with two species from the Lower Permian of eastern Australia and one species from the Asselian of Timor. These species appear to be primitive members of a group of species described from the upper part of the Sakmarian Series of the Urals.
