Re: Sauroposeidon (shoulder height information)



To all interested in the shoulder height of the new sauropod:  The URL for
"the Wire" that Betty gave us has a sketch of Sauroposeidon standing next to
a Brachiosaurus, Giraffe and human (no picts, sorry Nick :-) ).  On that
it's marked at 13' (look under "dinosaur graphic").  Do with that what you
will.
