 In contrast to the present Earth and its distribution of continental mass, Pangaea was centred on the Equator and surrounded by the superocean Panthalassa.Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.The name "Pangaea/Pangea" is derived from Ancient Greek "pan" (, "all, entire, whole") and "Gaia" (, "Mother Earth, land").
