That's interesting because that's not the concept Unwin wrote about  
in his JVP abstract (granted that was submitted months ago, but that  
was also months after seeing Bennett's Munich presentation two  
Septembers ago).

In the abstract, "New fossil evidence for a broad forewing in  
pterosaurs, "Unwin and Wilkinson stated, "…the articular condyle of  
the pteroid has a complex shape that is complimentary to the anterior  
cotyle of the medial carpal, within which it articulated..."

That's why I was interested in hearing what he would say and show.  
Sorry I missed it.

I wonder what inspired Unwin to change his mind? In any case, I'm  
glad that he did. I think he's on the right track. Which means  >>>>

And that's good.

Hopefully he's not still 'bent' on that anteriorly-oriented pteroid  
configuration idea, even if it was attached at the proximal  
syncarpal. Just say it ain't so...
