Well I think some people will say that Archaeopteryx is just another feathered dinosaur like Anchiornis huxleyi, Velociraptor..... rather that a real bird.
It is important to recognize that classification is a tool invented by human beings, not imposed by nature. We found a way classifcation useful to describe related, but does not clearly define the boundaries of the nature of concern and help us. It just becomes more complicated as we find more fossils to fill the gaps in the records. So, archaeoptyrex a bird-like dinosaur or dinosaur-like bird? It certainly has some features we do not usually associate with modern birds. But it is certainly more like birds than we tend to think, as a dinosaur. "If Archaeopteryx were discovered today, I don't think you would call it a bird. You would call it a feathered dinosaur," says Carrano. It's still called the first bird, but more for historic reasons than because it is the oldest or best embodiment of birdlike traits.Dinosaurs' Living Descendants It's just depends where you put the limit between birds and no-avian theropods.
