Coprolites

---

Welcome to our virtual coprolite exhibit, where you’ll find a wealth of information about some of the specimens in our rich holdings. We hope this information will inspire you to explore this fascinating subject matter further.

​The word “coprolite” comes from the Greek words Kopros Lithos, meaning “dung stone”. Basically coprolites are very old pieces of poop that have become fossilized over a very long time. Most coprolites are composed of calcium phosphates, silicates, and a small amount of organic matter. Coprolites come in a variety of shapes and sizes and they have been discovered on every continent on earth. These special little time capsules provide direct links to prehistoric animal diets, behaviors, and environments. 

It is extremely difficult to determine what ancient creature originally pooped the coprolite specimen. However, many prehistoric coprolites resemble modern feces. This helps Paleoscatologists (people who study very old poop) guess what prehistoric creature made the poop. Scientists and fossil enthusiasts have discovered coprolites that can be traced to tyrannosaurids, crocodilians, sharks, fish, termites, shrimp, and even humans.  Lastly, coprolites smell like rocks - not poop!
