200 MILLION YEARS AGO
The Supercontinent
200 million years ago, every continent on Earth was fused into a single giant landmass called Pangaea. Dinosaurs could walk from what is now North America all the way to Antarctica without ever crossing an ocean. The world was one enormous connected habitat β and the same dinosaur species roamed across all of it.
ONE!
THE CRACK BEGINS
Heat From Below
Deep inside Earth, convection currents in the molten mantle slowly pulled Pangaea apart. First came the rift valleys β enormous cracks splitting the land, filling with lava, then seawater.
TETHYS SEA
A New Ocean Is Born
As the rift widened, the Tethys Sea flooded in between. What started as a crack became a channel, then a sea, then a vast ocean β cutting off dinosaur populations forever.
