I really thought the explanation about the impossibility of the existence of the larger dinosaur skeleton was a joke. Was it? One serious assumption made was that the dinosaurs needed to lift things, even themselves. Perhaps the larger saurians NEVER SAT DOWN. If you weighed over 10 tons and had to eat for several hours of the day, wouldn't you avoid sitting? The other statements made involved the impossibilities of the blood pressure necessary to pump blood up 50 feet of neck. The giraffe can do it to 20 and the skeleton in question clearly shows the head about level with the body. The significant pressure comes from a differential between the heart and the head/feet, not the distance from the head to the ground. A plumber could do that math for you. Sure, they probably couldn't hold their heads high for very long, just as a fighter pilot can't handle 12 Gs for very long. The gravitational effect of all the planets combined is a small fraction of the effect of the moon upon the earth. The earth would need a ridiculous rotational speed for gravity to be significantly less apparent.
