Here's a bit of dinosaur trivia for you... Did you know that some plant eating dinosaurs had gastroliths? A gastrolith is also called a stomach stone. It is a rock held inside a gastrointestinal tract. They were used to grind food in the dinosaurs that needed a bit of help digesting the plant material. In our Prehistoric Museum, we have authentic gastroliths that came from the stomach of some of these huge plant eaters.
If you're like me, you're asking how do scientists know these aren't just regular smooth rocks? Because they've been found so many times in fossils of dinosaurs that scientists say they are not just a coincidence. And, because some animals have gastoliths today.
It's neat to hold a stone that's been in a dinosaur stomach. See all the cool things you can do at Dinosaur World?!
