Data may be retrieved in various timescale formats, such as Harland, Haq, Exxon or AGSO, and also different vintages of interpretive biostratigraphic data. The database currently contains over 800 wells, mainly from the NW Shelf, Gippsland, Otway, Cooper and Eromanga Basins. It has nearly 3000 zonation codes, with zonal schemes covering the entire Phanerozoic and all major fossil groups. This information is displayed graphically on the biozonation chart series .
