Gee, i notice that scapular is particularly bent, way more so than other in 
other hypsies. I
wonder how this may relate to a borrowing lifestyle.
Or is it just autopomorphic? Also, the skeletal reconstruction shows the 
scapular-corocoid to be
very massive compared to the humerus + antebrachium. Isn't this the opposite of 
what is expected
for a borrower?
