Palaeontologists have classified the fossilized remains of some 340 genera of Dinosaurs. Those depicted and listed here have been drawn to scale where possible, artistic licence was necessary in some cases. Not all those illustrated roamed the Earth at exactly the same period , though all were active at some time during the Mesozoic era. This drawing is based on the premise that if the Dinosaurs came back and the human race had become extinct instead, would they be as fascinated with our world as we are with theirs?
