Geologists contend that Pangea’s formation seems to have been partially responsible for the mass extinction event at the end of the Permian Period, particularly in the marine realm.As Pangea formed, the extent of shallow water habitats declined, and land barriers inhibited cold polar waters from circulating into the tropics.
