Dinosaurs evolved from carnivores to plant-eaters over millions of years. Key stages include early omnivorous species, then specialized herbivores with complex teeth and jaws.
- Early Carnivores: Early dinosaurs like Eoraptor were likely omnivores or small carnivores.
- Omnivory to Herbivory: Species like Lesothosaurus show early stages of plant-based diets with simple teeth.
- Specialized Herbivores: Stegosaurus and Iguanodon had complex jaw structures for processing tough vegetation.
Pro tip: The transition to herbivory was gradual, driven by environmental changes and the evolution of plant defenses.
