So the occasional messenger is screwing up the message.  Don't take it out
on the message.  I don't see many people outside of artistic liscensing
(i.e. some drawings) putting feathers on Allosaurus, with this new evidence
here, at least.

Again, there are lots of people who screw up scientific theories when
relaying them.  That shouldn't reflect on the theory itself.

Their validity as genera or as featherd animals?  I personally have spoken
to several sedimentologists, and, along with many geologists from the
geology department of the University of Minnesota, they invariably say that
NGMC 91 feathers cannot be preservational accidents, especially due to
sedimentary anomalies, and are the real thing.  Most biologists would
agree, based off of structural analysis.

I am not sure where the denial line is drawn, but I think there is clear,
overwhelming evidence to say that these are feathery appendages.
