Tyrannosaurus Rex, Sabre-tooth Tiger, Dodo Bird, Mammoth.
You all know them from movies and especially cartoons. But what are they... fiction or reality....Well, a ten year old child will tell you they are definitly reality. A reality from the past, though. They were extinct either milions of years ago, either centuries ago. They were victim of climate changes, natural disasters and in some cases ..human being. These are not the only examples.
