We filmed some backplate in Redwood Forests in Northern CA for our T.rex
episode on Reign of the Dinosaurs. Making the assumption that the terrain in
some T.rex environments may have been the same given the presence on
Metasequoia and Laurel forests we've been having a heck of a time finding a
"nice clear path" for the rexes to walk/run, even in the most well-groomed
forests. Given the fact that no one was cleaning up millions of years of
massive deadfall T.rex must have had to do some fancy footwork, as well as
ducking and crouching while ambulating through the forests at least some of the
time. Standing on slopes or even walking on them would require some constant
shifting of weight and balance.
