Pangaea started to break up during the Triassic Period. It continued to split apart in the Jurassic Period and was almost complete in breaking up in the Cretaceous Period. After that it formed into the landmasses that we see today.
When Pangaea broke up, species had to adapt to changing environments. Those species that could adapt, changed along with their habitats. Those that could not adapt died off.
Pangaea began to break up during the Jurassic period, around 180 million years ago. This breakup eventually led to the formation of the continents as we know them today.
