Many people have heard of Pangaea, the supercontinent that included all continents on Earth and began to break up about 175 million years ago. Wegener then assembled an impressive amount of evidence to show that Earths continents were once connected in a single supercontinent. Based on evidence that has emerged through the study of plate tectonics, it is likely that Pangea was not the only supercontinent to have existed.
