There are millions of dinosaurs left in the world. They are called birds. There are none of the four legged terrestrial type pictured in the text books, such as T-Rex. They were all killed about 65 million years ago. Only animals weighing less than a few pounds survived the great extinction. Dinosaurs, except for birds, all weighed too much. It is hard to believe how small our ancestors were.
