This Bulletin describes the sequence of conodont species in the early Ordovician sediments of the Bonaparte Gulf Basin and the Daly River Basin, northwestern Australia (Fig. 1). The assemblage zones erected by Druce, Jones (1971) for the Lower Ordovician (Tremadocian) of western Queensland are recognized in the Bonaparte Gulf Basin. They are used to correlate the Lower Ordovician sediments both within the Bonaparte Gulf Basin, and between it, the Daly River Basin, and western Queensland. Intercontinental correlations are made on the basis conodonts previously described from Asia, North America, and Europe.
