Dinosaurs and platypus are real. Archaeopteryx is a model version of Phoenix, belonging to dinosaurs and mandarin ducks. The flying species in the world are basically descendants of dinosaurs, otherwise history is not as early as dinosaurs. And the dragon, please refer to the new dragon. Mermaid is a relic of tens of thousands of years ago, eating grass. I heard someone witnessed it. I don't know if there is. But the world is full of miracles, but there are cannibals. Kun Peng is Kun, right? Legend has it that it ruled the earth earlier than dinosaurs, but prehistoric deified species such as Kirin may be based on the Cenozoic species tens of thousands of years ago. Hope to adopt, thank you.
