    Using a computer generated model to simulate sauropod neck movements was
a neat idea.  Obviously, you don't have as much freedom to play around with
the real thing, but my point was simply that the DMNH mount demonstrates
that it is possible to articulate the neck vertebrae (in at least one
specimen of Diplodocus) to get the head well above the horizontal without
dislocating the zygapophyses, because the head is high up and the
zygapophyses are articulating.  I haven't read Stevens and Peter's paper,
and I wasn't personally involved with helping to mount the sauropod neck, so
I can't explain the descrepency.
