Our story begins some 245 million years ago with a super continent named Pangaea in the Mesozoic era.Which has three periods the oldest triassic(245-208 mya)(short for Millions of Years Ago) then jurassic(208-146 mya) and the cretaceous(145-65 mya)era.
Pangaea (Greek for "all lands") was the supercontinent that existed before plate tectonics separated the major continents.Pangaea was believed to have formed 300 million years ago.The vast ocean that surrounded Pangaea has been named Panthalassa.Pangaea is believed to have broken up about 200-180 mya into two supercontinents Laurasia the continents of the northern hemisphere and Gondwana (originally Gondwanaland) which includes most of the landmasses which make up today's continents of the southern hemisphere, Including Africa and South America.
Gondwana is of intrest to us if you look t the pictures you can see The rift between Africa and South America occurs right in the natural range of the
remaining memebers of the Order Polypteriformes The polypterids.
