The dinosaurs were a group of prehistoric reptiles that ruled Earth for about 160 million years. People did not even know dinosaurs existed until the 1800's.

There is much still to learn, and the scientists of the future-the students of today-may be the ones who solve the mysteries of the dinosaurs.
