::: It's not common knowledge, because, as I said, I can find a number of sources that say that dinosaurs are reptiles. So I agree a source is needed. And I have two questions. 1) Is cold-bloodedness (still) considered a defining characteristic of reptiles (as distinct from a typical characteristic)? That is, does finding that dinosaurs are warm-blooded mean that they are not reptiles, or does it mean that cold-bloodedness is no longer considered an absolute requirement of reptilianness? 2) Have all dinosaurs been found to be warm-blooded, or just some?
