Why Don’t Land Animals Get That Big Anymore?

Why don’t land animals get as big as they used to? Prehistoric Earth produced enormous land animals — from giant dinosaurs and sauropods to massive mammals that dwarfed many species alive today. But modern land animals rarely come close to those extreme sizes. So what changed? In this documentary, we explore why prehistoric animals became so enormous, what limits the size of animals on land, how evolution, climate, food, anatomy, reproduction, and extinction shaped gigantism, and why the largest animals alive today are found in the ocean instead. The answer isn’t one simple change. Giant land animals disappeared because the world around them changed — and because getting huge comes with serious biological limits. #PrehistoricAnimals #Dinosaurs #Evolution #Megafauna #documentary
