The acritarch C. peifferi sp. nov. from the Devonian Chattanooga shales in northeastern Tennessee, USA, has a characteristic arrangement of polygonal areas, or fields, on the central body. Two distinct kinds of fields, polar and subequatorial, differ in form and symmetry. Fields are arranged according to a constant tabulation pattern (1:5:5:1) with pentagonal symmetry developed around the polar field on each hemisphere.
