Gondwana between South America, Africa, North America, and Europe. CAMP covered more than seven million square kilometres over a few million years, reached its peak at , and coincided with the Triassic–Jurassic extinction event. The reformed Gondwanan continent was not precisely the same as that which had existed before Pangaea formed; for example, most of Florida and southern Georgia and Alabama is underlain by rocks that were originally part of Gondwana, but this region stayed attached to North America when the Central Atlantic opened. Antarctica, the centre of the supercontinent, shared boundaries with all other Gondwana continents and the fragmentation of
Laurasia including West Virginia, Britain, and Germany. Siberia moved southwards and joined with Kazakhstania, a small continental region believed today to have been created during the Silurian by extensive volcanism. When these two continents joined together, Laurasia was nearly reformed, and by the beginning of the Triassic, the East China craton had rejoined the redeveloping Laurasia as it collided with Gondwana to form Pangaea. North China became, as it drifted southwards from near-Arctic latitudes, the last continent to join with Pangaea. Around 200 million years ago, Pangaea started to break up.
