Pangaea was a supercontinent. This enormous continent was consisted of all continental masses on Earth that merged together in the late Paleozoic era, around 335 million years ago. Pangaea lasted until the early Mesozoic era, breaking apart roughly around 175 million years ago. From the breaking apart of this supercontinent there were two large masses that formed, Laurasia on the north, and Gondwanaland on the south. As these two remnants of Pangaea continued to break apart, the modern day continents started to form and slowly started to give the planet the appearance that we see in the present.
