So Various reasons...

>and that they may have had boyant gas filled organs that mitigated some of their weight as well.
>>9535330
>#2. Increased levels of co2 is what allowed giant insects/creatures, not increased o2. The latter is just an assumption people make.
>>9529317
>Energy availability is the reason. How many times do i need to explain this?
>>9529178
>I don't know what allowed sauropods to have a monopoly on trees, but i suspect it to be plain old long co-evolution.
>>9529071
>Oxygen is a meme. Animals evolve to be larger when increased body size increases reproductive success
>>9527025
>Pretty sure whales don't need to support their weight so their size wasn't capped structurally
>>9526236
>Another reason for the greater size in dinosaurs is that they laid eggs, which allows them to get rid of their children faster.
>>9525325
>Diet is the reason for sauropod size. Grass didn't evolve yet and they needed large size to harvest trees.

>Whales live in water so they have a lower metabolic load than if they were supporting themselves on land.
