A variety of paleogeographic reconstructions have been published, with applications ranging from paleoclimate, ocean circulation and faunal radiation models to resource ex- ploration; yet their uncertainties remain difficult to assess as they are generally presented as low-resolution static maps. We present a methodology for ground-truthing the digital Palaeogeographic Atlas of Australia by linking the GPlates plate reconstruction tool to the global Paleobiology Database and a Phanerozoic plate motion model. We develop a spatio- temporal data mining workflow to validate the Phanero- zoic Palaeogeographic Atlas of Australia with paleoenviron- ments derived from fossil data. While there is general agree- ment between fossil data and the paleogeographic model, the methodology highlights key inconsistencies. The Early De- vonian paleogeographic model of southeastern Australia in- sufficiently describes the Emsian inundation that may be re- fined using biofacies distributions. Additionally, the paleo- geographic model and fossil data can be used to strengthen numerical models, such as the dynamic topography and the associated inundation of eastern Australia during the Creta- ceous. Although paleobiology data provide constraints only for paleoenvironments with high preservation potential of or- ganisms, our approach enables the use of additional proxy data to generate improved paleogeographic reconstructions.
