A cool article about a new dinosaur dug up. It's part of the raptor family, but it predates most flying dinosaurs by a several million years. So it is possible the flying dinosaurs may have been around during the Jurrassic period (about 206 to 144 million years ago) then died off during the first mass extinction, then over several million years developed flight again.

Interesting.

Sure, I don't see why not. If the conditions match, I'd say that any species can develop such traits.

But we already know powered flight evolved more than twice...

It evolved once in birds, once in insects, and once in mammals, and even once in fish (hatchetfish, not flyingfish which actually glide and so do not count as powered flight). So really what they're saying is that it might have evolved five times (six, if you count humans). It's only twice for the bird/dinosaur (ornitho-saurian?) branch.

Twice seperately in a related species, not overall. I guss I shoulda rephrased that.

So what you're saying is the the whole story of Jesus is just an allegory for the development of flight in dinosaurs. Thus proving that dinosaurs and man walked the Earth at the same time and therefore that the Young Earthers are right.

Wow, I feel so misguided.

That's why there was a mass extinction. He messed up and started over.

8 if you count flying spiders.
A few more if you count plants' seeds that glide or catch the wind.

That's why I made the distinction of powered flight. Spiders, seeds, flying squirrels, flyingfish, and hang-gliders don't count.

All flights are powered, at least by the wind. You should have said self-powered flight.

Powered flight commonly refers to exactly that. The Wright brothers have the distinction of creating the first, heavier than air, powered aircraft. Successful gliders had already been created. Hatchetfish have actual powered flight in which they flap their pectoral fins to maintain their altitude while flyingfish merely glide. This is fairly standard terminology.

Actually, the Wrights had the first heavier than air, sustained, controlled, powered flight.

Samuel Langley tried to launch his aircraft, the "aerodrome" off a ship twice before the Wrights' momentous flight. Hiram Maxim made many aircraft in the 1890's. Many others were doing the same, but noone was successful until the Wrights.
