Psittacosaurus, a small ceratopsian dinosaur from the Early Cretaceous period, is known for its beak-like mouth and bipedal stance. It inhabited forests and plains of what is now Asia, showcasing parrot-like skulls and quills on its tail, possibly used for display or defense.

Psittacosaurus is native to Asia, specifically the regions that are now part of China, Mongolia, Russia, and possibly Thailand. Fossils have been discovered predominantly in the Yixian Formation and the Jehol Biota in northeast China, as well as in the Gobi Desert of Mongolia.

Psittacosaurus lived during the Early Cretaceous period, approximately 126 to 100 million years ago. The environment was likely semi-arid with distinct wet and dry seasons. The landscape included floodplains, river valleys, and possibly forested areas with coniferous trees and ferns.

Psittacosaurus was a small, herbivorous dinosaur that likely fed on a variety of vegetation including ferns, cycads, and possibly seeds. Its beak and cheek teeth suggest it was well-adapted for processing tough plant material. As a ground-dwelling dinosaur, it likely occupied a niche similar to that of modern-day small herbivores, contributing to seed dispersal and vegetation management in its ecosystem.
