Dinosaurs roamed the land. Some of the
largest animals ever to walk the Earth
were the huge plant-eating sauropods.
Some small dinosaurs developed feathers,
probably for insulation, and later some
developed the ability to fly, and in doing so
evolved into birds.
When Pangaea broke up, it created two
smaller supercontinents, Laurasia and
Gondwana. Gondwana, which included
Australia, extended from the Equator to
the South Pole. Throughout this period,
Australia drifted south.
Conifers, ferns and cycads dominated the
landscape and it was during this period
that the first tree-ferns appeared.
