It might seem hopeless to try to reconstruct the original supercratons but it is not. Dike swarms act like fingerprints that allow one to determine the original positions of the currently existing cratons. https://tok.fandom.com/wiki/Proto-Supercratons

<p>With plate tectonics, supercontinents split up into smaller continents, and then the smaller continents get mashed up together to form a new supercontinent. There used to be a single supercontinent Pangea, and before that there was Rodinia. How many times in the past have all the continents been smashed up together into a single supercontinent?</p>
