| Zusammenfassung |
| A variety of paleogeographic reconstructions have been published, with
applications ranging from paleoclimate, ocean circulation and faunal
radiation models to resource exploration; 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 Phanerozoic
Palaeogeographic Atlas of Australia with paleoenvironments derived from
fossil data. While there is general agreement between fossil data and the
paleogeographic model, the methodology highlights key inconsistencies. The
Early Devonian paleogeographic model of southeastern Australia
insufficiently describes the Emsian inundation that may be refined using
biofacies distributions. Additionally, the paleogeographic 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
Cretaceous. Although paleobiology data provide constraints only for
paleoenvironments with high preservation potential of organisms, our
approach enables the use of additional proxy data to generate improved
paleogeographic reconstructions. |
