The first birds appeared 150 million years ago, evolving from dinosaurs long before ''Unenlagia'' lived. Therefore, it is not an ancestor of modern-day birds, but was an evolutionary dead-end. The most bird-like dinosaur ever discovered is the 90-million-year-old ''Unenlagia comahuensis'', a flightless, 4-foot tall, 7.5-foot-long carnivore. [[Category:Dromaeosauridae]] {{biology-stub}}
