Now we know that they were competent quadrupeds.

But this trackway abruptly.

I think that that's where they named the flying reptile off.

Well, now you're making me nervous.

So it's a winged reptile-like bird.

But they found this trackway that suddenly became much longer stride, which means it started sprinting.

Whoa.

If you look up...

Quetzalcoatl compared to a giraffe they were like sprinting around so they thought forever that they had to jump off something to make flight but now we know that they were able to go fast enough to make their own flight so this thing is they're as big as giraffes they're as big as giraffes they can fly and they're predatory and it's believed that they're probably the only thing around that would have given Tyrannosaurus Rex paws whoa in a fight T-Rex could obviously win but imagine being able to sprint because that spear would do some damage

Yeah.

So imagine like you're driving at that thing in a car.

It could take off before you hit it.

You know, I don't know.

It's just nuts.

Yeah, I thought it went up even more recently than that.

I suspect that there was a lot more civilization than we know about going on in North America particularly, but everywhere else too.

No.

Because wasn't it only the Caucasus and Africa, I believe?

That's a big mystery in my opinion.

I mean, right now the best hypothesis is that primates came over on floating vegetation.
