Kent Stevens.

This was, indeed, his Black Hills presentation!
Stevens, K.A., E.D. Wills, P.L. Larson & A. Anderson. 2005. Rex, sit: modeling 
tyrannosaurid postures. (second title: Making a
Scanned Stan Stand). "100 Years of Tyrannosaurus rex" A symposium.

Kent and his colleagues used a scan of Stan in DinoMorph, and showed several 
alternative models of how it could rise. There aren't
any real problems, and there are a number of solutions.

Why people don't ask the questions "could bigass titanosaurs lie on their 
sides?" or "what happens when a Brachiosaurus trips?" I
don't know.
