Psittacosaurus

Psittacosaurus is a genus of small ceratopsian dinosaur that lived in Asia during the Early Cretaceous between 126 and 101 million years ago. It was named and described by the paleotologist Henry Fairfield Osborn in 1923 after it was discovered in Mongolia. In the "new world," numerous Psittacosaurus herds are spread throughout the northern hemisphere. They are closely related to larger ceratopsians such as Centrosaurus and Triceratops.
