WebThe break-up of Rodinia is understood better than its formation. Extensive flood basalt flows and volcanic eruptions of Neoproterozoic age are found on most continents. This is evidence for large scale rifting about 750 million years ago. As early as 850 and 800 million years ago, a rift developed, eventually becoming an ocean in the Ediacaran. WebAs Pannotia drifted apart, it formed slightly smaller supercontinents (Laurentia, Baltica, and Gondwana) that eventually slammed together to form Pangaea about 200 million years ago. The most famous supercontinent had a good run, though — Pangaea didn’t really start to break up until the Early-Middle Jurassic Period (175 million years ago). red case tractor
