PALEOMAP Digital Elevation model

A paleo-digital elevation model (paleoDEM) is a digital representation of paleotopography and paleobathymetry that has been “reconstructed” back in time. It can be used to produce detailed paleogeographic maps. The paleoDEMS describe the changing distribution of deep oceans, shallow seas, lowlands, and mountainous regions during the last 540 million years at five million year intervals. Each PaleoDEM is an estimate of the elevation of the land surface and depth of the ocean basins measured in meters (m) at a resolution of 1×1 degrees.
