Wait a second Dave - unless I've missed your point - all I see
there is Wellnhofer drawing the fingers in that position - he
doesn't "demonstrate" it. Wellnhofer could be wrong (indeed, I
think he was wrong about this).
Excellent. There should be, and I think there are, a few fossil
examples of wing fingers completely deployed. Can we look for and
talk about those examples? Either on-list or off-. Your choice. I
don't want to bore anybody with pterosaur trivia.
Also, no thoughts on Wellnhofer's reconstruction of digits I-III
torsioned 90 degrees anteriorly on the standard configuration
I vote wrong on that too.
Here I agree with you. Chris Bennett follows Wellnhofer.
Thank you, John. This is reminding me of the American elections.
There's another favorite candidate in every state.
