I'm afraid I can't agree.  Recent work on _Triceratops_ has lead to the=
 conclusion that sprawling forelimbs actually do coincide with trackway=
 data.  I recently had the pleasure of talking with Bruce Erickson, from the=
 Science Museum of Minnesota (who's collection has one of the few=
 non-plaster mounts of _Triceratops_, placed in a sprawling posture).  By=
 measuring the width between the feet, he was able to put together a=
 composite of what trackway his T-tops would make.  Suprise, Suprise, the=
 composite track coincides with the dimensions of a real trackway.

Therefore, and back to my original question, since split posture types are=
 possible, could this also be accurate for other quadreped dinosaurs?
