Psittacosaurus, meaning 'parrot lizard,' was a small, primitive ceratopsian, a plant-eating dinosaur. |
|
The Psittacosaurus was a strong, agile dinosaur with a powerful beak. A plant-eater, it lived in northeastern Asia between 144 million and 97 million years ago. |

The skeleton was later identified as belonging to a Psittacosaurus. |

The use of gastroliths for digestion seems to have developed on the line from basal theropods to birds, with a parallel development in Psittacosaurus. |
