Continental drift.

Near the end of the Paleozoic era (250 MYA), the major landmasses moved together into the supercontinent Pangaea.

Some effects of Pangaea on life include:


  • a reduction in shallow water habitat.
  • a drier and colder climate inland.
  • changes in climate as continents through latitudes.
  • changes in ocean currents leading to global cooling.
