Dinosaurs were one of the first animals on earth.

The Tyranosaurus is known to be the deadliest of all the dinosaurs.It was known to be as long as a bus and as heavy as two elephants on top of each other.All dinosaurs were known to live over 6 billion years ago.Lots of archeoligists find many dinosaur fossils, most probably in Africa.The legend of dragons comes from dinosaurs even though dinosaurs did not breathe fire.Although dinosaurs did not breathe fire, they had the weight of a supposedly real dragon.Some people think dinosaurs were not real and dragons were, such as young boys who are growing up and do not believe in Santa claus.Dinosaurs are used in the most boring shoujen [Japanese animes for boys 10 and over] even though boys find them interesting.Dinosaurs were reptiles but bigger than others. The birds were their closest species to them, as most dinosaurs could fly but some could not.
