Crocodile ancestors found in Sahara
All of the prehistoric crocs lived about 100 million years ago in the southern super-continent known as Gondwana, when the region that is now the Sahara featured dinosaurs and grassy plains criss-crossed by rivers.
"These species open a window on a croc world completely foreign to what was living on northern continents," Sereno said in a statement.
The new croc fossils are described in the journal ZooKeys and will feature in the November issue of National Geographic magazine and in a special airing Saturday on the National Geographic Channel."
Gondwana (or Gondwanaland) was a composite continent, made up of South America, Africa, Madagascar, Antarctica, India, other parts of South Asia, and Australia. At one time it even included Florida and most of Southern Europe.
Gondwanaland is named after the Upper Paleozoic and Mesozoic formations of the Gondwana district of central India, which display a number of shared geologic features (the "Gondwana beds"). In the late nineteenth century, on the basis of comparative geological evidence, the Austrian geologist, Edward Suess, suggested that the continents of Africa, South America, Australia and India were once part of a single supercontinent, which he called "Gondwanaland".
Science tells us that the Continents of Australia, India, South America, Africa, and Antarctica, existed together as a separate landmass as long as 650 million years ago. And as these continents only began to break up some 130 million years ago, this great supercontinent had a life of around 520 million years; making it perhaps the most important geological structure of the last billion years.

This is what Gondwanaland looked like:

It is fascinating that a species such as the crocodile appears to have originated in a desert isn't it? Crocodiles are reptiles and reptiles can live in both land and water, however, it is obvious that crocodiles need water to survive. So how did these ancestors of the crocodiles get their water living in a desert??
