Humans and lemurs are both primates. And some people theorize that both chicken and dinosaurs are aves. If you ask me, all dinosaurs were birds and some survive until today, makes more sense then some dinosaurs were birds and it's just those that survive. But I'm not a paleontologists. And what bugs me is that we have all manner of lizards, even huge turtles and crocodiles and warm blooded birds, but not a single small dino. There being no huge dinos makes sense, but if we have Nile crocodiles and ostriches, why not one chicken sized dino? |

Um, no. Birds are members of the larger dinosaur family the same way you are a member of the primate family. They are dinosaurs in the way that you are a primate, but they aren't dinosaurs in the way that you aren't a lemur.
There was a time when a whole host of other animals were a part of this family, but they have died off. The entire group of animals is collectively known as dinosaurs, but since birds evolved and were proven distinct prior to the extinction, it is correct to say that birds are a subset of dinosaurs, not that all dinosaurs were birds.
People who speculate that such a split is incorrectly classified, and that birds are simply evolved dinosaurs have a pretty big uphill climb in my opinion. The presence of fossils that show that what we would classify as birds living before the extinction is a pretty major hurdle.
