Psittacosaurus sinensis was a small, herbivorous dinosaur which lived around 126-101 million years ago. It is one of the earliest known ceratopsian dinosaurs. It was named after the Latin word for parrot, Psittacus, as it had a parrot-like beak.

Psittacosaurus sinensis was a plant-eater that had:

  • a curved, parrot-like beak that helped it to pry open fleshy cones and seeds
  • short forelegs that it used for grasping foliage.
