No, because _Compy_ and the other tyrannosaurians ultimately descended from a
small volant dino-bird, perhaps an enantiornithan, with only two claws
remaining in its wings. This ancestral form was a more advanced dino-bird
than _Archy_ in having lost manual digit III. Or at least, this is the most
likely hypothesis in my humble opinion...etc.
