Around 110 million years ago, a dinosaur ate some plants, in what is now western Canada, before suddenly dying. That creature is now giving important information about ancient plant-eating dinosaurs. Scientists reported recently that fossilized contents of the creature's stomach were found along with its skeleton. The fossils were discovered in the Canadian province of Alberta. They are said to be the best-preserved remains of any plant-eating dinosaur. The stomach contents even show the cellular structure of leaves from the plants the dinosaur ate.
