Rodinia

Hypothetical Neoproterozoic supercontinent

In the geological history of Earth, Rodinia (from Russian родина (rodina) 'motherland, birthplace') was a Mesoproterozoic and Neoproterozoic supercontinent that assembled 1.26–0.90 billion years ago (GaTooltip gigaannus) and broke up 750–633 million years ago (Ma). Valentine & Moores (1970) were probably the first to recognise a Precambrian supercontinent, which they named "Pangaea I". It was renamed "Rodinia" by McMenamin & McMenamin (1990), who also were the first to produce a plate reconstruction and propose a temporal framework for the supercontinent.
