Deinonychus is a type of dinosaur that lived a long, long time ago. It was big, had sharp claws on its feet, and was really good at hunting. It liked to live and hunt with its friends, just like how we play with our friends! Deinonychus had long legs and a long tail that helped it to balance when it ran really fast. Can you imagine how exciting it would be to see a real Deinonychus?
