If you looked up at the trees 120 million years ago, in what is now northeast China, you might have seen a bird-like creature about the size of a crow.
"Microraptors" were a type of flying dinosaur that had four feathered wings and lived during the early Cretaceous period. They used their feet to hunt prey, like hawks do today.
Now, an international team of scientists has found that these ancient creatures had more in common with today's birds than they thought.
Much can be learned from the shape and size of bird feet. They show a bird's grasping ability, running skill and feeding style.
The microraptor fossils show that the extinct animals behaved like the predatory birds of today, and would hunt similar kinds of prey.
