Abstract

Conodonts from the Fairfield Group, Canning Basin were examined in order to determine both the sequence of species and the age of the Group. This work is part of a larger study of the latest Devonian and Early Carboniferous rocks exposed on the northern margin of the basin. A total of 57 form species referable to 21 form genera and an additional two multi-element taxa are described: two multi-element species, lcriodus platys and Pelekysgnathus australis, and one form species, Spathognathodus canningensis, are new and one form species, Hibbardella helmsi, has a new name. One multi-element taxon and fourteen form species are left in open nomenclature. Six assemblage zones are recognised although the endemic nature of the fauna and differing ranges of form species from those recorded elsewhere preclude accurate correlation with other sequences in Australia and overseas. However, a broad correlation is presented. The two lowest assemblage zones are latest Devonian and are present in the Gumhole Formation and the lowermost part of the Yellow Drum Sandstone. The upper four assemblage zones are Early Carboniferous (Tournaisian) and are present in the remainder of the Yellow Drum Sandstone and the Laurel Formation.
