What are coprolites?

Coprolites are fossilized poop from really old animals, sometimes even dinosaurs!

Imagine you have a pet dog that eats everything and goes to the park every day. One day, you find its poop in the grass, and it’s still there 10 years later. That's kind of like what coprolites are, except they're way older, maybe millions of years old!

When an animal poops somewhere and then gets buried under dirt or sand, over time the poop turns into rock. This process is called fossilization. Just like how your favorite toy might look different after being in a box for years, the poop changes too, it becomes harder, smoother, and sometimes even has little bits of food inside.

Scientists love coprolites because they tell us what ancient animals ate. If there are tiny bones or plant pieces inside, that means the animal was eating meat or plants! It’s like finding a lunch bag from someone who lived millions of years ago, but made of rock! Coprolites are fossilized poop from really old animals, sometimes even dinosaurs!
