How Did Dinosaurs Get So Huge?

The video explores why dinosaurs were so large compared to mammals, focusing on biomechanical differences, reproduction methods, and evolutionary advantages. Dinosaurs like the Titanosaur Patagotitan reached enormous sizes due to features like air sacs that lightened their skeletons. In contrast, mammals have dense bones and longer gestation periods, limiting their size. The video also discusses potential reasons for the dinosaurs' large size, such as predator avoidance and food access, and questions whether being large was truly advantageous, given that only birds, a small group of theropods, survive today.
