Although plate tectonics is an important cornerstone in modern phylogenetic biogeography, it is currently used either as subjective dispersal parameter between poorly predefined areas, or as a *post-hoc* inference after the analysis. Here, a new phylogenetic biogeography method is presented. The method is (1) based on cladogenetic (vicariance,full copy sympatry, point sympatry, and jump dispersal), and anagenetic events (dispersal, extinction); (2) it is explicitly geographic, using a geographic data model (a raster) and ranges of any size in both terminalsand internal nodes, instead of predefined areas; (3) the geography is dynamic, so the position of each pixel is estimated using an explicit tectonic model, which might include paleogeographic data (emerged land,epicontinental seas, glacial ice sheets). Implementation details, an empirical example, and potential expansions are also discussed.
