In Apple's "Prehistoric Planet", two male Dreadnoughtus dinosaurs challenge each other, displaying gular throat sacs.

There's no fossil evidence of these, but the titanosaurs did have extensive air sacs in their bones, so it's possible.

But here's MY question: Why did they have such long necks?

That continues to today, with electric and internal combustion engines, all of which date back to the Latin term for "innately clever". Engines are the work of engineers who are ingenious. 🙄

But none of that beats a trebuchet.

So while Asiatic lions are still Endangered (IUCN Red List), the conservation efforts are having the desired effect, and we can hope that they continue to thrive, ensuring that our children's children will share a planet with that symbol of strength & ferocity.
