No dinosaurs can breathe fire. Although some extinct ancient creatures can spray liquid substances, they do not belong to the category of dinosaurs.
For example, there was an animal called "Stegosaurus" in the order Ornithischia that once lived on Earth. It had large bone plates on its back similar to swords. Some scientists speculate that these bone plates may be involved in behaviors such as thermoregulation and display. In addition, a duck-billed dinosaur called "Hadrosauridae" can also spray a large amount of clear water through oral glands to defend against natural enemies.
In short, dinosaurs are a type of extinct ancient creatures. Their main characteristics are limb support, bipedal walking, huge body, and diverse evolution. They have survived on Earth for tens of millions of years, providing us with important information and data for studying the evolution of life.
