I saw that Chicxulub crater and I would think that a meteorite would make a circular crater, not a square one. It's probably a mining site.

Lovely graphic and a great explanation.
The elephant in the room though is that it's really hard to be sad about the extinction of dinosaurs.
I saw a documentary in the 80s called Jurrassic park which showed how bad things could get on a small island if Dinosaurs were still alive - just imagine the mischief they could get up to now in Greater london !
Come on scientists, get real ! Let's hear a belated cheer for epoch defining interstellar asteroid impacts !

Hmm.... Instead of saying or just believing, or just getting to that point. About the millions of years and such.... because it's only a theory that, that happened. So why are they so sure? I'm not saying that because I'm a christian >.> I'm just wondering why they believe that to tell the truth wouldn't we have run out of resources? If the world was that old. Well I know resources grow and reproduce so we can survive, but how could a species exist that long?

There were no humans at the time.
It is a pretty viable theory since the (likely) impact site has been found, and you can also find a thin layer of sediment worldwide in between rock layers of the age in question, which is consistent with dust settling after the impact.
google "Chicxulub crater"

Very interesting video. What evidence is there to show this event took place 65 million years ago? Why would all the dynosaurs have been wiped out?
-
It must have been a large asteroid.
How did humans survive?
This is not a viable theory if it is based on Evolution.

I thought that scientists nowadays have come to agree more on the hypothesis that the K/T extinction was to blame on a dramatic series of events that culminated in the asteroid impact, though this was just a tiny droplet to overflow the glass...
-
me not scientist but there is a huge issue there is no impacts or debris large enough to cause the layer the suggest
i think something more closer to ground caused it im thinking of the formation of pacific plate as in a larva flow spewed ash into the air maybe triggered by change in gravity or sun emition
similar event will maybe repeat one day on very much smaller scale somewhere like yellow stone park in usa

The sound on this is bad. Why the rock music? I can't hear the scientist. I can only hear the interviewer and the TOO LOUD music.

Not sure we understand? This clip has no music on it?
