“Then you explain how these huge animals stood up and walked around under one G gravity. “

You yourself said that another explanation is that they had more powerful muscles.

Frankly if I were to pick between the gravity being different and dinosaurs had different muscles. The different muscles explanation is a far more likely scenario. And I’m not sure why any one would opt for the different gravity theory except to be deliberately shocking.

Muscle tissue is nearly identically the same for all vertebrate animals; there’s no way to think dinosaur muscle was better than ours.

Look up big G. I mean what Mr. Dirac had to say about it. The laws of physics ARE only models. Reality is reality. Basic "constants" can change -- as we learn more. We make many gross assumptions about the constants applied over space and time.

Oh, and the reality is the world is flat, too. The assumption of local flatness -- over the area a man may walk in a day, is an accurate one.
