World-famous “Dung Detective” Dr. Karen Chin explains how coprolites (a.k.a. fossil feces) tell stories that bones cannot tell themselves—like which plants and animals lived together in the ancient past. And who was eating whom. And how waste isn’t bad, but is, in fact, a very important part of the process of living! This is Step 5 nonfiction at its most fascinating! From the Trade Paperback edition.
