Early Ordovician conodont distribution from craton to basin and island terranes in East Gondwana

Early Ordovician conodonts are documented from sporadic outcrops along a transect of more than 1000 kms across New South Wales (N.S.W.), extending from the cratonic margin of east Gondwana to oceanic islands and basins of the Proto–Pacific Ocean. Tectonic settings of these outcrops and their localities are discussed in an accompanying article (Percival and Glen, 2003). The restricted age range of these faunas (upper Prioniodus elegans to Oepikodus evae zones) permits analysis of conodont distribution across a variety of near–contemporaneous depth–controlled environments within the Tropical Domains of both the Shallow–Sea and Open–Sea Realms (Zhen and Percival, 2002, 2003).
