Dinosaurs seemed to have generally been so much larger than animals today. Huge dragonflies that dwarf their modern counterparts, turtles 10ft long. What is the mechanism that allowed them to be so large, or conversely makes modern ones smaller? Is it about Oxygen levels, or efficiency, or something else?

First I’d ask if you ever saw a dinosaur (I have not) and are you certain we’ve reconstructed and guessed their true environment accurately or where they came from at all.
For example how do we know they didn’t have additional extremities made completely of cartilage that dissipated leaving only the bone structure as a fossil. Lots of what ifs while the initial narrative is simply accepted because well, it was the initial narrative and that’s a propagation of how human psychology works in general of any topic.
