What ate the Psittacosaurus?

Psittacosaurus, a small herbivorous dinosaur from the Early Cretaceous period, primarily fed on a diet of plants, including leaves, seeds, and possibly fruits. Its beak-like mouth and teeth were adapted for grasping and processing tough vegetation. Fossil evidence suggests that it may have also consumed some softer materials, such as flowers or ferns, indicating a varied diet suited to different habitats.
