Paleogeography

Map showing the paleogeography of the Middle Permian (272.95-259.1 MYA). Three settings are mapped: land (>0m elevation), shelf (-200m–0m), and deep ocean (<-200 m). Shelf areas ring the land. On the map the supercontinent Pangaea forms a “C” shaped landmass centered more or less on the equator. The ocean surrounded on three sides by the “C” of Pangaea is the Paleo-Tethys Ocean.

. Map showing the paleogeography of the Middle Permian (272.95-259.1 MYA). The fossils from the McHugh Complex limestone are more similar to deposits that formed in and around the Paleo-Tethys Ocean (seen in the center of the figure). This suggests that the rocks those fossils are found in were formed near the Paleo-Tethys Ocean, and subsequently transported across the Panthalassa Ocean to Alaska by the movement of the oceanic plate.
