I'm not sure that extraordinary discoveries do get a free ride. Note the
skeptical responses to the venomous _Sinornithosaurus_ paper (published in
PNAS). Alternative interpretations to _Balour_ having a 'double-bladed' foot
also got an airing on the DML.

I wholeheartedly agree. However... the trouble is that there is no unanimity
with regards to "we". For example, many of us have become jaded with the
BANDits deriding/dismissing any and all fossil discoveries that link birds to
dinosaurs. "_Microraptor_ has wings, and so therefore it must be a bird" and
similar nonsense. So I don't think it is necessarily helpful to immediately
question the veracity of a discovery just because it goes against "our"
In the case of the "quill knobs" on _Concavenator_, you originally wrote:
"Sad, it really just reads like the authors want these to be quill
knobs more than anything else. Maybe the actual paper offers better
Thus, you (1) queried the authors' motivation in making such an interpretation,
and (2) expressed your skepticism prior to even viewing the paper (and the
authors' reasoning therein). Although you are quite possibly correct in your
skepticism regarding quill knobs on a carnosaur, the very concept alone should
not immediately invite skepticism (or cynicism). To me, it is quite reasonable
that a carnosaur might have had feathery arms and a scaly body.
Note, if _Concavenator_'s 'quill knobs' actually denote an intermuscular line
rather than anchor points for feather homologs, then the question of whether or
not _Concavenator_ had feathers is still open.
