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?
