Re: scaling dinosaurs
Perhaps they were skinnier. But the bones were not. Modern animals with thicker bones have more muscle and skin on those bones than their smaller relatives. I see no reason to think that dinosaurs were different. for the tails being skinnier, at proportionate distances from the main body of the animal the tails and necks are proportionately larger. When you hand a neck vertebrae that would be in the same position on a smaller dinosaur but is twice as tall, thick, and wide then the odds are that the neck in that location is also twice as tall, thick and wide.
Ok, I see where you are going. I will say we must differ at this point. You are suggesting a thickness that doesn’t resemble what I (or you) have seen in nature.
Make that “have a neck vertebrea”
