Dinosaurs with no teeth include species like Berthasaura leopoldinae, a toothless theropod dinosaur with a beak-like mouth discovered in Brazil. It likely was an omnivore despite lacking teeth, using its beak to eat various foods.
On the other hand, one of the dinosaurs with the most teeth is Nigersaurus, a sauropod from the Cretaceous period, which had over 500 teeth arranged in a wide vacuum cleaner-like muzzle. Its teeth were constantly replaced approximately every two weeks, helping it feed on low-lying vegetation. This dinosaur was herbivorous and roamed what is now the Sahara Desert.
Summary
- Toothless dinosaur : Berthasaura leopoldinae, a small theropod with a beak and no teeth.
- Dinosaur with many teeth : Nigersaurus, with over 500 teeth replaced frequently, specialized for herbivory.
Thus, there are both kinds of dinosaurs — some with no teeth, having beak-like mouths, and others with hundreds of teeth, adapted to their specific diets.
