How Old is Fossilized Dinosaur Poop? Fossilized dinosaur poop, or coprolites, typically date back to the Mesozoic Era, which means they are anywhere from 65 million to 230 million years old. These ancient fossils are time capsules, preserving evidence of what dinosaurs ate and how they lived. The age of a coprolite is determined by the geological layer in which it was found, with older coprolites being more rare and valuable. For fossil enthusiasts in the United States, owning a piece of fossilized dinosaur poop is like holding a piece of history in your hands, a tangible connection to a time when dinosaurs roamed the earth. These ancient relics are not only fascinating for their age but also for the stories they tell about life on our planet millions of years ago. Whether you’re a collector or simply intrigued by history, the age of a coprolite adds a profound depth to its significance.
