Research suggests millions of years ago, migrating dinosaurs traveled to Wyoming on a full stomach of stones from hundreds of miles away.
Research conducted by scientists at the University of Texas discovered new information on the life and times of Jurassic dinosaurs in Wyoming. But the discovery didn’t come from dinosaur bones – it came from dinosaur stones.
Gastroliths are smooth, shiny stones often found next to the skeletons of long-necked dinosaurs like Brontosaurus. They called trace fossils – not bones or teeth, but something left behind by a prehistoric creature. Footprints and coprolites – fossilized poop – are other examples of trace fossils.
