Re: Another feather theory

It certainly sounds plausible - although if feathers were increasing in

have been to make the potential prey look larger than it actually was.
Imagine if a small Sinosauropteryx-like theropod puffed out all of its
protofeathers, erected a suddenly bushy tail, and backed up the display
with an aggressive open-mouthed hiss. It might have been enough to make
a potential predator (or rival) think twice.
By appearing larger it could also affect the aim of a predator's lunge.
