Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. Scientists agree that continents rest on rocks called tectonic plates, which shift and move. Wegener published this theory of continental drift and claimed that it was supported by several pieces of evidence and that these areas were once joined. It has been suggested that the next supercontinent will form in 200-250 million years, so we are currently about halfway through the scattered phase of the current supercontinent cycle. Scientists have long noticed the similarity between the two coastlines, but it was not until the 20th century that evidence could support a theory that the continents were once connected.

Modern day representation of the Lystrosaurus. 'S see what happens if we add the idea at the time rejected hypothesis! The explanation for their movement is due to the theory of plate tectonics. The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist.Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.Late in the Triassic Period (which lasted from approximately 251 million to 199.6 Wegener proposed that the organisms had lived side by side, but that the lands had moved apart after they were dead and fossilized. There has only been one magnetic north pole and the continents have drifted (figure7). Areas of South America and Africa have rocks of the same age, around 550 million years old, and composition.
