n. A supercontinent that existed during the Late Precambrian before the supercontinent Pannotia; the oldest supercontinent for which we have a good record; Russian for "homeland."

A proposed Precambrian supercontinent that existed around 1 billion years ago.

In geology, Rodinia (from the Russian родина, or "motherland") refers to one of the oldest known supercontinents, which contained most or all of Earth's then-current landmass. Paleomagnetic evidence provides clues to the paleolatitude of individual formations, but not to their longitude, which geologists have pieced together by comparing similar strata, often now widely dispersed.
