Danny, Dino Doc is a paleontologist who appears in Neat Stuff To Know & To Do. Vinny Brontosaurus seeks him out when he wants to know how scientists can figure out what a whole dinosaur looks like based on the findings of one bone fossil. Danny explains the process, beginning with how they first decide what part of the body the bone would have been from. For example, if it was a leg bone, paleontologists can determine the size and weight of the dinosaur's body by looking at how long it is. He likens it to finding a tire from a car, and deciding how much that tire was designed to support on the vehicle.
