Abstract: As part of an international study of Devonian facies movements against cratonic
       areas an investigation has been undertaken of the timing of facies movements associated
       with the Frasnian and Famennian reef complexes of the Canning Basin, Western Australia.
       This led to the discovery of rich goniatite faunas which enable significant improvements to
       be made to the high resolution ammonoid time scale.  A new goniatite classification for the
       Frasnian is proposed for  international use based on the entry of particular genera; this gives
       12 divisions.  A much more detailed regional zonation is proposed for the Canning Basin.  As
       part of this, a description is given of the following new genera of the Gephuroceratidae:
       Gogoceras, Playfordites, Serramanticoceras and Mixomanticoceras.  The genus Probe-
       toceras is used in a restricted sense and recognised as the first member of the Beloceratidae;
       Acanthoclymenia is used for forms previously assigned loosely to Probeloceras.
         T'he new zonation provides a framework for analysis of facies movements.  Occasions of
       anoxic or hypoxic events are indicated by rich, hematized goniatite faunas, Reef
       backstepping associated with deepening is dateable by goniatites in associated marginal
       slope deposits.  Several of the international eustatic sea-level changes are recognised,
       noticeably those correlative with the Genundewa, Middlesex and Rhinestreet deepenings
       of New York.  No evidence has been found for the internationally widespread 'Kellwasser-
       kalk' facies in the late Frasnian, but a succession of terminal Frasnian sea-level changes is
       recognized.  The 'lridium Anomaly' level lies well above the Frasnian/Famennian
       boundary and hence provides no confirmation of a bolide to explain Frasnian/Famennian
       boundary extinctions.  In the Famennian, evidence tot the European Condroz regression
       and Annulata deepening is presented.
