What if you woke up one morning with a dinosaur's body part instead of your own? If you suddenly had a Velociraptor's sharp toes, you'd be able to shred anything that came your way. If you sprouted a Brachiosaurus's long neck, you could see over any crowd. And if you discovered you had a Parasaurolophus's head crest, you'd be the loudest kid at your school! Being part dinosaur would be pretty cool. So if you could have any dinosaur's body part, which would you choose?
