So much of what scientists know about dinosaur diets comes from a gross place--poop! Fossilized dinosaur poop is called coprolites. It's a bit easier to find carnivore poop because it's full of hard parts like bones that fossilize better than the plants herbivores ate. Nonetheless, we know a lot about what different kinds of dinosaurs ate! Readers investigate dinosaur science in the colorfully illustrated pages of this book. Its content supports knowledge building, a key component of the science of reading.
