Continents can be made to fit together like a piece of jigsaw puzzle, also the similarity of the Atlantic coastlines of Africa and south America was also recognized so Alfred wegener in the early 1900s made a strong case for continental drift , he noted that south America, Africa,India , Antarctica, and Australia had almost identical Paleozoic rock and fossils. He then reassembled the continent to form a giant super continent which he called pangea , his reason was that the similar rocks and fossils were easier explained if the continent are joined together.
Explanation:The fossil record helped to support the idea of pangea becos these fossils were found in all 5 continent as at that time so it could only be possible if these continent were actually joined together for example the fossil remains of land-dwelling reptiles Lystrosaurus and Cynognathus are found in Triassic-age rocks on all the five continent, also the plant Glossopteris is found in Pennsylvania and Permian-age rock on all five continent
