What is a yin long dinosaur?

The Yinlong is a small, herbivorous dinosaur that lived during the Late Jurassic period, approximately 160 million years ago. It belongs to the group of dinosaurs known as Ceratopsia, which includes later well-known species like Triceratops. Fossils of Yinlong have been found in China, and it is characterized by its distinct features, including a relatively large head and a beak-like mouth adapted for grazing. Its discovery has provided valuable insights into the early evolution of ceratopsians.
