You can read about how dinosaurs moved around on wikipedia if I remember right. :unsure:
You might be able to read up on theories of how they moved on wiki, and other places, but it's still mostly guess work. The best models we have today for dinosaur movement is modern species, such as birds (the closest modern living relative of dinosaurs and likely a descendant).
I have heard that dinosaurs like tyrannosaurus may have had a locomotion that was like a cross between a large bird and a reptile. While it does have feet that are like a muscular version of, oh say, an ostrich's feet, we still need to add the tail into the equation as it would also effect how the animal moved around. And since there's no modern animal today with a body built like a dinosaur like tyrannosaurus, one can only speculate how they might have moved.
