You need changes of density for that.

Like how wood is more dense than air but (generally) less dense than water.

So it floats on water, but doesn't rise into the air.

The air might be really really dense, but it would only help that wood "float" if it were more dense than that wood.


(Dense air might help wings work better, but that's a different thing...)
something was bugging me about this line of argument ...

dinosaurs (and insects) didn't need to float; they only needed to support their own weight ... >>thinking: whales and ocean critters<<

increased atmospheric density => reduced density gradient (difference);
it does improve bouyancy ...
