Who Dung It? The Science of Fossil Coprolites

Join us for a fascinating, hands-on lecture exploring the science of coprolites—fossilized feces left behind by creatures ranging from tiny insects to massive dinosaurs. While many are familiar with prehistoric animals, few consider the clues they left behind on the "other end."

Through the study of coprolites, scientists uncover valuable insights into the diets, digestive systems, and ecosystems of long-extinct species. You’ll learn how paleontologists use these ancient remnants to reconstruct prehistoric life and behavior.

This engaging talk will introduce you to the experts who study this enigmatic material and include a variety of real coprolite samples to see and touch.

Come travel back in time with us and discover what ancient creatures really left behind!
