The Jurassic constitutes the middle period of the Mesozoic era, also known as the Age of Reptiles. also, The Jurassic is named after the Jura Mountains within the European Alps, where limestone strata from the period were first identified. By the beginning of the Jurassic, the Pangaea had begun rifting into two landmasses, laurasia to the north and gondwana to the south, hence I hardly think that this will happen again.
