Re: Pro(to)avis



Again, more'n one way to skin a cat. In what flight position does it hold its hindlimbs? If tucked forward in flight with knees bent, no cg problem, and no hindwings required -- the tip fan alone will do the job of holding the tail up.

I would suggest that animals that had only a tip fan on their tails could be
more likely than others to have hindlimb wings.

Plus, I forgot to add that *Shenzhouraptor* (including *Jeholornis*) has such a tip fan, but so far no "hindwings" have been found. Osteologically the animal does not appear flightless...
