Positions come from the plate model of Merdith and colleagues (2021), through the GPlates Web Service of the EarthByte Group at the University of Sydney. The globe shows today's coastlines carried back with their plates, not the shorelines of the time, so it does not say whether a place was land or sea. Cities and their coordinates come from Wikidata.
