RE: Pangolin bipedal walking
As Viv and a bunch of others have shown, most theropod depictions have massive
shrink-wrap syndrom. That affects the tail more than other body parts. As a
consequence, the actual COM is further back than it seems. Same for many other
dinosaurs. Check Plateosaurus:

What do you mean by carrying capacity? There have been a few quantitative
studies of tail mass and how it affects the position of the centre of mass.
I did one of them:
