I thought the dinosaurs were killed off by a comet. Or a volcanic eruption. Or an ice age.
Certainly not because it got warmer. Dinosaurs like it warm.
They were killed off by a global flood and the drastically different climate that followed.
Dinosaurs created global warming via farting, which led to more dinosaurs since they liked the warmth, which led to more farting, more dinosaurs and so on until one fine day an asteroid entered the atmosphere, igniting all that methane, blowing dinosaur carcasses plumb underground. That’s how they got there. Natural gas is ancient residual dinosaur fatrs.
