Article: Astrocystites distans sp. nov., an edrioblastoid from the Ordovician of eastern Australia

A new Ordovician edrioblastoid, Astrocystites distans sp. nov., and other miscellaneous pelmatozoan plates are described from the lower part of the Cliefden Caves Limestone WNW. of Mandurama, New South Wales. The edrioblastoid is similar to the only other species of Astrocystites known, A. ottawaensis Whiteaves from the Trenton Limestone of Ottawa, which was hitherto the sole representative of the group. This represents the first record of an edrioblastoid outside North America. Sections of the Australian material have revealed details of internal structures not previously known in the group.
