I thought O2 was higher during the time of the dinosaurs? Maybe that was earlier... I don't remember when the time of the big bugs was.

Big bugs were in the carboniferous, about 350-300 million years ago.

Dinos didn't evolve until about 240 million years ago, and didn't take over the world until about 200 million years ago. T Rex evolved quite late as far as non-avian dinos go, only about 68 million years ago.

You could be right... that far back it's easy to mix up which millions and millions of years you're talking about
