Re: vaulting pterosaur launch: I give up
Illustrations will be forthcoming when I have the time and energy to
do it right - those sorts of technical illustrations require time and
patience (not to mention a lot of precision), and I am reluctant to
just rush off something rapid. I can do some actual "sketches" in
short order, in the rough and quick sense, but they'll only give a
rough idea - hardly appropriate for detailed critiques.
I wouldn't become too overly focused on illustrations as
demonstration, in any case. Visualizing a dynamic process like launch
is very helpful, but the illustrations themselves are more a depiction
of the conclusions than a source of evidence (and leave lots of room
for artistic license, if not constrained by quantitative evidence).
The evidence really comes, in this case, from the structural mechanics
and quantitative analysis. I'd be more than happy to chat further
about the numbers, which really make the case, or the specific
qualitative characters that further bolster the argument. I'm also
happy to provide illustrations, but that will require some time - I'm
rather swamped writing manuscripts at the moment.

Good luck. Hope you're right.
At the risk of opening up a new torrent, in your hypotheses, do
pterosaurs stick landings?
