What features did dinosaurs have to survive?

Some grew larger, some began to walk on four legs, and others grew into different shapes. Each new feature, a long neck or sharp teeth, or bony plates, if it helped the animal survive, was passed on to later generations. These features became the hallmark of each new kind of dinosaur.
