Great video, well presented, and Shane has SUCH clever turns of phrase! Enjoying this series quite a bit!
The thing that astonishes and dismays me most is that - while we were doing all of this to get whale oil - how much of the other whale products ended up being wasted? I know in some parts of the world whale meat was eaten and so in those areas maybe the animals did get used (though perhaps when speaking of industrial level hunting we can't say used "with respect" ) - but what did people do with those carcasses? I know that in cultures where whales are taken specifically for survival, there's not a single part of that creature that isn't used for something, so what I'm curious about it just what the "Civilized World" did with those parts that weren't rendered down for oil or eaten. Whale bones for corsetry, perhaps? But how much bone did that really use? It makes me curious.
I know most of the time we think of industry (especially the industries of a hundred years ago) as being wasteful and terrible and kinda the source of all our current troubles, but I feel like that's an oversimplified view. Not so much inaccurate as incomplete. We got where we are through many, many small steps, after all, and getting through this predicament will take many, MANY small steps as well. I do believe we can repair our planet, and even manage to do it in about the same amount of time it took us to break everything. But I'm always interested to learn the complexities of HOW we got here, what people did to survive, to thrive, to turn a profit or to eradicate something they saw as terrible. Folks don't go around killing whales while twirling their mustachios and yelling MUAHAHA, so it's always fascinating to understand what drove the choices made by our ancestors.

Pterygota, or mayflies, is order of flyers from the Silurian and Devonian has some older fossils than of meganeurids, apparently, up to am estimated 440 million years ago, that is more than a hundred million years earlier! (I was also surprised, thought the same as you).
But still, that is one "that we know of".
Insects, especially with softer and lighter exoskeletons sadly do not fossilize very well. So it is very scarce, especially that far back. From most we even only have fragments of wings.
But it also seems more likely that flight would probably have started with a much smaller insect rather than the more massive and specialized Odonata.
Also, they would require their niche (hunting other flying insects) to exist before being able to evolve into that niche of course.
