For this reason, the existence of Mesosaurus helps support the theory of continental drift; that is, the now-well-attested fact that South America and Africa were joined together into the giant continent Gondwana 300 million years ago before the continental plates supporting them broke apart and drifted into their current positions. About 18 hours later, the Puyehue volcano erupted, triggered by all the activity in Earth's crust.
