This maps show palaeo-drainage basins at the global scale for all rivers of the world applying a flow accumulation algorithm to the General Bathymetric Chart of the Oceans (GEBCO). The maps also show the number of current drainage basins included in each palaeo-drainage basin and the similarity levels of their fish species composition.
