120 million years ago it lived in what is now China. Cratonavis zhui was about the size of a medium-sized hawk and definitely was a bird. It had wings and talons, it had a wishbone, albeit shaped a bit differently from modern birds. It appears to have been a predatory bird like a raptor.
It had a skull identical to t-rex. No beak. No ability to raise the upper half of the jaw like modern birds. Just a regular dino head.
It appears that beaks and bird skulls evolved after the ability to fly as part of a refinement of it.
Or it's just a small dragon.
