Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. Diane’s favorite "casting character” of all time wasn’t dead, famous, or even human. In March 1997, the National Zoo in Washington, D. C., asked her to make casts of the paw and tongue of a living tiger for an exhibit. Tiger paws have sharp claws, and the tongue is sandwiched between four long, meat-ripping canine teeth. But Diane wasn’t worried about her safety, since the big cat would be tranquilized. She was more worried about the tiger. She didn’t want to harm the animal in any way. She didn’t know—yet—how to cast the body part of a living animal, especially one so large and . . . predatory.
