Pangolin bipedal walking

["Richard W. Travsky" <rtravsky@uwyo.edu>]

One thing that has always bothered me is the depiction of bipedal 
theropods, at least for the bigger ones. They always seem like the CoG 
was forward of the legs and they should fall on their chins.

I came across a youtube video of a (giant?) pangolin (and looked at a 
couple others) and noted that I get the same (and probably wrong) 
impression about them.

Their tail seems to have a lot of weight to counterbalance the bipedal 
walking. However, the skeleton of a giant pangolin

gives little visual hint that it could be carrying weight. So, can the 
carrying capacity of such tails, pangolin or theropod, be estimated?
