Read the excerpt from "Bone Detective," by Lorraine Jean Hopping.

Next Diane borrowed Mary’s cat, Whites, for a dress rehearsal of the big event. Mary told Diane that cats vent body heat through the tongue. To avoid overheating the animal, she recommended using cold water—and working quickly.

When Mary tranquilized her cat for its regular teeth cleaning, Diane made an impression of the little pink tongue. She had to work around an oxygen tube in the cat’s mouth. But, once again, she was able to produce an amazingly detailed impression. It included all the spines that made the cat’s tongue so rough. Cats need the stiff bristles—called filiform papillae—to clean their fur. Diane wondered what the tiger tongue would feel like—a scrub brush?
