Is a giraffe a dinosaur?
No. Brachiosaurus was a dinosaur that lived around 150 million years ago. … It takes less time to evolve longer bones than it does to change the total number, and this is an indication that the giraffe is more closely related to humans than to dinosaurs. In fact, our ancestries diverged just 110 million or so years ago.

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.
