I'll tell ya the difference! Your leg, is something you walk, and kick with, whereas your arm, is something you grab, and throw with. That's not the technical difference in dinosaurs obviously but look at Tyrannosaurus for example. Its legs have three toed feet, whereas its arms have only two fingers. Some dinosaurs such as Spinosaurus may've been able to get down on all fours but that's not the point. What the point is however, is that yes, dinosaurs had four legs. No, not all of them.
