Re: wing extensor placement on pterosaurs

True enough. E. coli is also at the top of its game. The acme of its
genre. But it doesn't have an elongated metacarpus.
Still hanging out here in St. Louis waiting to see how anyone can get
metacarpals I-III to move _above_ the wing finger extensor when they
are clearly ventral to it in primitive pterosaurs, as demonstrated by
Wellnhofer 1991. I think you can't get there from here.
Also, no thoughts on Wellnhofer's reconstruction of digits I-III
torsioned 90 degrees anteriorly on the standard configuration
