Dinosaurs evolved from reptiles. They became so successful due to an improvement of body structure. If you've noticed a lizard, you've seen that their legs are kind of sprawly, coming out at the sides of their bodies. Dinosaurs put their legs undertheir bodies so they could support their weight on their bones instead of straining their muscles.
At about the same time dinosaurs were developing new legs, another group of reptiles was experimenting with specialized teeth. These became the mammals. For a while, it looked as though the teeth specialists would become the dominant group (they could eat more different foods), but as it turned out, specialized legs were the more important factor.
