What features did dinosaurs have to survive?
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. Certain groups, like the sauropods, thrived during the Jurassic Period [about 210 – 145 million years ago].
