Rodinia (from the Russian родить, rodit, meaning “to beget, to give birth”,[2] or родина, rodina, meaning “motherland, birthplace”)[3][4] was a Neoproterozoic supercontinent that assembled 1.1–0.9 billion years ago and broke up 750–633 million years ago.[5] Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named ‘Pangaea I’.[5] It was renamed ‘Rodinia’ by McMenamin & McMenamin 1990 who also were the first to produce a reconstruction and propose a temporal framework for the supercontinent.[6]
