I meant no criticism of Parrish's work.  It was precisely the strangeness of 
sauropods that I was alluding to -- Well.  OK.  I admit to being snide about 
the use of phylogenetic bracketing to deduce behavior.  But that has nothing to 
do with the sauropod neck study.  The neck problem is simply another example of 
the fact that sauropods are, as you very aptly put it, weird.  "Weird" in the 
same sense as "quantum weirdness".  Almost nothing about them makes intuitive 
sense.  The low-neck model helps solve the blood pressure problem, but then why 
bother with a long neck if you can't elevate it, not mention the mechanical 
problems connected with feeding...
