<<Matt, I'm not sure I followed what you're saying here.  To me it seems 
that hind leg first landings would be easier to accomplish.  Is that 
your point as well?>>

I think Caple et al. argue otherwise and say that controlling direction 
is hard for bipedal arboreal animals.  

<<The pterosaur wrist casts I have here show no geometric similarity 
whatever to bird wrists.  They allow a similar motion, but do so with a 
very different structure.>>

Exactly.  Bat wrists are different from bird wrists, but they provide a 
similiar movement.  Thanks.

Thanks.  Sorry, but I won't be able to get to the Snowbird SVP this 
year.  Maybe I'll make it next year wherever it is going to be.
