Just skimming for what I was interested in, I don't see anything to suggest that a thicker atmosphere would provide support for a large land animal.
That would require structures in the animal kept at below ambient pressure. e.g. heated air sacs
- lazide 5y agoAlso basic density calculations doesn’t favor the theory. Even at 100bar, even with some weird composition difference (but not completely bizarre like sulphur hexaflouride) the atmosphere is on the order of 10-20kg/m^3. Even with the most implausible ‘what a dinosaur is made of’ theories I can come up with, unless the larger dinosaurs were born carrying around 100+ m^3 balloons full of helium, it doesn’t seem doable. There literally isn’t enough space in them to have enough sacs of lighter than air gas for that to make sense.
