You haven’t even read Feduccia’s book(s), have you?
You should understand that most of those unconvincing dinosaurs with fuzz have been redefined as birds by Feduccia after later specimens have been found with true feathers. For example, Veliciraptor, which Feduccia once swore could not possibly be related to birds, all the characters shared with Archaeopteryx convergent, etc., is now a flightless bird, perhaps occasioned by the discovery of Microraptor. Collagen fibers transformed into feathers instantly! And no, “fuzz of this kind” in pterosaurs and ornithischians is rather different, though it may indeed by homologous. Note also that calling anything with feathers a bird does nothing to affect the relationships among species, and of course an animal can be a bird and a dinosaur at the same time: groups within groups.
So you’re arguing against Feduccia and the other BANDits. More quote-mining.
