What was pangaea? when did it form and when did it break apart it was

Pangaea was a supercontinent. It is the last supercontinent that had all of the continental masses joined as one, though after its breaking apart there were two other supercontinents which were very short lasting. This supercontinent formed from the pre-existing continental masses that moved toward one another and merged by the late Paleozoic era, approximately around 335 million years ago. Pangaea existed until the early Mesozoic era, and it started to break apart around 175 million years ago. From the breaking apart of this supercontinent, initially formed Laurasia and Gondwanaland, and from the further breaking apart of these two we got the modern day continents.
