Rodinia is a relatively famous supercontinent that existed towards the end of the Proterozoic Eon. Nevertheless, many
people don't know it. It existed from the Stenian
period to right before the Cryogenian
period encompassing nearly all of the Tonian
period.
It was almost exactly on the opposite side of where Pangea formed. It turned inside out during the Cryogenian
period to become Pannotia, leaving out exposed rocks that sucked up carbon dioxide, thus causing a snowball earth. Pannotia somehow still didn't make it into the Phanerozoic Eon.
Rodinia wasn't by itself unlike other supercontinents. It had a continent to the west of it as its companion. Made of parts of South America and Africa, this continent was called Congo. While Rodinia turned itself inside out, Congo got caught in between the two halves, completing Pannotia.
Jack who lives in eastern South America: Bruh, my point 800 million years ago was in Congo and not in the rest of Rodinia. Why were the bacteria that lived where I am not able to party with everyone else until 720 million years ago? I feel
bad for them.
Kate who lives in western
Africa: The bacteria that lived where I am partied with the bacteria that lived where you are for billions of years! Don't feel
bad when it comes to paleogeography or paleontology. There are
always good things behind terrible extinction events and isolation from everyone else.
