Y u not read my post? >:I

Lets face it, Ankylosauruses are the biggest badasses ever.
latest

I mean look at this fucker. If you were a predator in the cretatous period, you'd probably think "Nope...I'm staying as far away from that thing as possible"

No argument there, they are bad mofos!

They also had amazing proportions

^Doug Henderson, AMAZING paleo-art, google him. Old master, bearded mountain man, but just humbling artwork! Few artist are as anatomically accurate, which has the habit of making his dinosaurs look a bit "off", but that's only because he focuses on realism rather than coolness.

Is that a large asteroid in the last image?

It is!
I hope we get to see one of these, like baby 99942 Apophis, well, when I'm old and sick of all this shit anyway
I kneel under the night sky, and gaze up, and speak - come Apophis, come make a mockery out of all human progress, make a joke out of our history, and wipe us from the face of this world!
 
From a realistic standpoint tho, I'm pretty sure asteroid impact didn't look like that.

What's your concern with it?
To me it looks realistic enough, a projectile burning with friction. I guess in reality, it would have been much brighter, comparing with the one in Russia a couple of years back, it was much smaller, but lit up the morning hours like a second sun.
One of the K-T dimensions would probably be so bright, that a depiction would be pointless, just a big blank white surface

I like this one too, day before I guess :D

That is air itself bursting into flames, and it's also what would happen with an asteroid, and one large enough would make flames appearing as if straight, because the oscillations would be too small to see from such a distance.
Again, though, at the massive scale of that asteroid, it would probably just be blindingly bright, to human eyes.
 
From a realistic standpoind tho, it's not depicting the impact, but the entry.

That too, it's supposedly a snapshot of the moment before it touches the ocean far beyond the horizon. He is playing with perception.
Here's an impact painting he made, but I can't find better, bigger versions

Either way, it's difficult to really imagine explosions that big, because we humans have never seen anything like it, not even close. The Tsar-bomba was just a fire-cracker in comparison
 
I want to see dinosaurs with feathers and shit like they are supposed to be. George Lucas needs to remake Jurassic Park at once.
 
The thing is that the asteroid itself was about 10km long, right? And Earth's atmosphere is 16km "thick" (speaking of the part that where majority of the actual gas is).
I can't recall the exact speed it was travelling, but that fucker would have passed through Earth's atmosphere in a very, very short amount of time. There would be friction and light, but I doubt you'd be able to see its trail or anything. At the moment it was hitting the surface with its front end, the rear end would be on the other end of the atmosphere (assuming it too the ideal position of front to rear end, so to speak, but you get my drift). Head in the ground, butt in outer space. All in one second.
Either way, I don't think there was any actual entry that you would've witnessed from that distance. No trail, nothing. Just light and death.

We can't know what it looks like untill we see it, but you have to take into account that friction begins much higher that 16 kilometres, especially with such a large object. Again, the painting plays with perception, the flames you are seeing are not at cloud height, but much, much further out.

There's at least the mesosphere, with vapor, to pass through, 80 kilometres.
Above that there's enough matter to cause aurorae for hundreds of kilometres

Again, I mostly just want to know what it would look like :V
 
Uhm, yes we can. That's what science is there for.
Of 'course' you can not make a photograph of it that would be 100% accurate to the real impact, if that is what you're asking for, but we can pretty much calculate the impact, use existing ones that we observed and extrapolate it to get a pretty accurate idea of what it might have looked like.

Correct me if I am wrong, but what Atom is trying to say, (I think?) is like if you tried to take a snapshot from a nuclear explosion the moment it happens. The only thing you really see is the mushroom cloud, but the actuall detonation, is just a split second of light and heat.

I agree with that though. It would just burn our eyes out, and there would be nothing for us pose and selfie with
Again, the closest thing we have (except sciency dumb-ass discovery channel renditions EYEROLL!!!) is the Russian asteroid, which pretty much just blinded everyone, for then to "detonate" and give a 100 000 people terrorist-attack-trauma :D
 
However, it sounds reasonable to assume that there would be no trail or at least nothing that you could really catch, I mean that thing would move with 30 000 meters per second or something like that? Or maybe even more? No clue.
Still, I don't think it's a question of imagination, I mean there is a lot of research when it comes to impacts and I think scientists understand that pretty well. Particularly today, get the data, throw them in a computer, run some simulation, done. As long as the informations you collected, like size, velocity etc. are correct, you should be possible to get a fairly accurate image/idea. And just like Atom, said considering the size a so called 'planet killer' needs at the very minimum, like a few km in diameter, to create this kind of damage and crater, it's fair to assume that it would have passed the atmosphere in like no time.

Anyway, we are just talking about the artists depiction of what it was in his head, it doesn't have to be necessarily 'realistic', just good looking.

I never thought about it, but now that we're already talking about it, I guess that a lot of shows and movies get that part wrong, where the impact takes probably way to long of such large objects. *Shrugs*, not that it ever bothered me. But it sure must be something that drives astrophysicists crazy. JEBUS FUCKING CHRIST! WHY IS THAT BLOODY THING ON THE SCREEN! You're not supposed to 'see' it coming!
