Facts about Dinosaurs
Dinosaurs were reptiles that lived on Earth from about 230 million years ago to about 65 million years ago. They were really big and some of them even had feathers. They lived on all seven continents. Their extinction was caused by a giant meteor that hit the earth. Most of the paleontologists believe in a theory stating that these huge reptiles evolved into birds. The first discovery of dinosaur remains in North America was made in 1854 by Ferdinand Vandiveer Hayden during his exploration of the upper Missouri River. These fossils belonged to Trachodon, Troodon, and Deinodon.
