Hmm. I think that now it _is_ time to move on and accept that Dinosauria includes birds. But we may as well be honest with ourselves and admit that the scientists who made it so screwed up. Everyone knew what "dinosaur" meant. It would have been better to discard the taxon Dinosauria when it became apparent that it was paraphyletic, define a new name for the clade (_Iguanodon_ + _Megalosaurus_) and let everyone keep on using the well-established vernacular term to mean what it always meant.
But I realise that ship has sailed.
Quite so.
Same with Reptilia.
