Wasn't there a significantly higher concentration of oxygen 65 million years ago or something? That might make it easier for big things to get enough oxygen for aerobic processes.
I don't know shit about fuck with chemistry and biology it just sounds right
Maybe it depends where you would cut a human head of? In either way here is the skeleton of a Argentinosaurus:
That looks like a way too small heart for such a huge body. It looks only about 3-4 times bigger than human heart
Oh, is that what that is? Thank you!
I'm not sure either but it's my best guess
