Troodon was a type of dinosaur that lived a very long time ago. It was smaller than some other dinosaurs and had razor-sharp teeth. Troodon had big eyes, which helped it see well, especially in the dark. It was very smart and could learn things quickly. Troodon liked to eat meat, so it was a carnivore. Even though Troodon isn’t around anymore, scientists can learn about it by studying its fossils.
