Ooh ooh! This is really cool, it’s actually a math thing called the square-cube law. Basically, any creature is limited in size by how much oxygen they can absorb, and since oxygen has to be absorbed by a 2-d surface like an alveoli, and the square-cube law is a math thing that says no matter what shape you’ve got going on, volume will always grow faster than surface area and you will outpace your ability to get bigger. It’s the natural law that puts a ceiling on how physically big a living thing can be. However! This growth limit can be offset if the air contains a higher concentration of oxygen! Which the Cretaceous period did! So everything was able to get bigger!

I've heard because the more oxygen and pressures in the atmosphere the bigger everything is.....including the bugs....

But maybe we should be asking “why are we so small?”

I looked it up, and the internet said that plants were large but mostly lacking in nutrients because they were still learning how to plant so animals had to eat more so they became bigger, and because the plants were virtually everywhere most animals became herbivores. To escape predators/stay safer from predators the herbivores great super large, and in turn the carnivores grew larger to compensate. With the climate shifting the plants stopped being able to grow so big so the herbivores started to die off or get smaller and humans starting to hunt out the larger animals very proficiently. Historians call it a “perfect storm” but basically the earth could no longer support such large life 🤷♀️

Multiples factors including hollow bones, air sacs throughout their body, reproductive methods (instead of birthing live young they laid eggs), to name a few! Blue whales are larger than any dinosaur because they essentially develop in zero gravity and have very nutrient dense prey.

To eat the tops of the trees while the little guys ate the lower ones?
