Many types of dinosaurs did not chew their food - but used their sharp teeth to cut large pieces of food, which they swallowed without chewing. These dinosaurs used powerful stomach muscles and stones (gastroliths) to grind up their food. We can see many types of birds and other animals still doing this today.
