This is a great educational gift or "gag" gift! Dinosaur droppings (coprolite) have proved equally crucial for modern-day scientists. Occasionally, archaeologists stumble across huge, well-preserved pieces of fossilized dinosaur dung?or “coprolites,” as they’re politely called. By examining these fossils in detail, researchers can figure out if they were created by plant-eating, meat-eating, or omnivorous dinosaurs?and they can sometimes even identify the type of animal or plant that the dinosaur ate a few hours (or a few days) before going Number 2.
