Unenlagia is the most bird-like dinosaur found so far - it even had arms that were designed so they could flap like a bird's wings! However, this dinosaur was much too large to fly, but it clearly shows how some dinosaurs were evolving to look and act like modern birds. Some scientists think that Unenlagia is actually a young Megaraptor  as the fossils were found in the same area.

Unenlagia is from the same general family that also includes many of the dinosaurs that exhibited bird-like traits, including those falling into the popular raptor category. It had a very pronounced backward-pointing pubis, and it appears as though its shoulder was designed to allow for flapping movements.
