Protoceratops Facts for Kids — The Egg-Guarding Dinosaur Nature Picture Book
What makes Protoceratops so amazing?
About the size of a sheep, Protoceratops is a small herbivore dinosaur—an ancestor of horned dinosaurs like Triceratops. It's also very famous for its egg fossils.

Nature and science facts about Protoceratops
Protoceratops lived about 75 million years ago in the deserts of Mongolia and China. Its eggs took about 83 days to hatch, and each egg was around 20cm long. Its eyeballs were about 5cm across—twice the size of human eyes. Thanks to those big eyes, it probably saw well even in dim places. Nests and egg fossils were found together, which helped us greatly in understanding how dinosaurs reproduced.
