Very simple script, (proof of concept) for making paleogeographic reconstruction based on output from GPlates (https://www.gplates.org/).
Need folder, Global_EarthByte_GPlates_PresentDay_Coastlines, containing the coastlines of ancient times for each interval with template reconstructed_<million years ago>.gmt. In this case, each increment is 1 million years. These are created by GPlates.
