Re: Pteromimus and pterosaur origins

You guys would know better than I, but last I looked, pedal digit V in basal pterosaurs may be long, but it still only consists of two phalanges.

Indeed. I was just making the general point that even reversals in phalanx number are possible.

That certainly suggests to me that it's been re-elongated

To me, too, but of course another possibility is that the claw was lost because it was unnecessary, like in the 3rd to 5th fingers of bats other than *Onychonycteris*.
