Answer 1

Although the species we recognized as dinosaurs went extinct, their descendants did not. The children of the dinosaurs are called birds. When the world changed, the dinosaurs had to change with it. Dinosaurs changed into birds over millions of generations, with each child of each dinosaur looking a tiny bit more like a bird. Well, not really each child, but the children that did look a tiny bit more like a bird tended to survive and have children of their own, while the children that looked more like a dinosaur tended not to survive and have children, because the world was not a good place for dinosaurs to live, and it was a good place for birds to live. So birds were more likely to survive than dinosaurs. And now we have birds, but no more dinosaurs.
