Large limestone outcrops, like the one pictured here, are evidence of these periodic incursions of continental seas. The Paleozoic Era is bracketed by the times of global super-continents. The era opened with the breakup of the world-continent Pannotia and closed with the formation of Pangea, as the Earth's continents came together once again.

Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time.
