Just before the days of the dinosaurs the Earth's
continents were all connected into one huge landmass called Pangaea .
This huge supercontinent was surrounded by one gigantic ocean called Panthalassa.
Notice the postion of the continents of Antarctica (Far north of its
current position), Australia (flipped sideways and far west of its
current position) and the subcontinent of India (Hundreds of miles from
Asia).
Scientists believe that the North American continent was located much
farther south and east of it's position today. In fact, much of North
America was in or near the tropics!! How do scientists know this??
They have found fossils from this period of time. These fossils are of
tropical plants and animals. The fossils have been found in cold regions
like North Dakota and Greenland!!!
