rcarter2 : Agreed, I tried to make the fact that it wasn't making
an agrguement just adding a bit more information about it for Ms.Coral...And I'm sorry if any of this came off the wrong way.

What killed them?
Something or Someone got rely rely Hungry.

I think what killed the Dinosaurs was a meteor that hit earth causing ash to cover the sun . The first Dinosaurs to go was the plant eaters because no sun = no plants .

I have to go with the meteor theory to me it's the most reasonable reason

Natural Selection, with the cooler temperatures with the up and coming Ice Age they wouldn't survive.  Plus mammals started becoming more prevalent and probably ate their eggs.

Take it for what you will, but apparently it has been recently confirmed by this article that asteroids did, in fact, kill the Dinosaurs.

As such, it doesn't really change my ideas so much, as I already actually believed in this theory from the start.

Walruses. It was definitely their fault.

I believed in the Meteorite theory, rather, as of this week, fact before the discoveries confirmed two days ago, but it feels pretty good knowing that I was right.

Humans killed the Dinosaurs, most of them anyways, There are still a few around the belgin Congo that live in the swamp. 
 
Here's how it went: 
 
 1. The Dino's got off of Noah's ark, God told Noah that the animals were now afraid of him So the Dino's ran off and has kids. . . 
 
 Your saying Whoa! red flag How do you know that Dino's were on the ark? well God said to take two of EVERY kind of animal and that' included Dino's. "Well how did they fit on the ark" you might ask, well If you have half a brain and 1 eye you would take Babies because.  . .
 
 #1 they eat less 
 
 #2 they weigh less 
 
 #3 they sleep a lot more 
 
 #4 there tougher 
 
 #5 they will produce more offspring when the flood is over, and that's why were bringing them! 
 
 So anyways the Dino's run off and hid in the wilderness 
  
 Noah's family grew and repopulated the entire world.
 
 And as they did the drove off the Dino's or as they called them back then. . .Dragons. . .  (the word Dinosaur wasn't invented untill 1789 So of course your not going to find it in the Bible)
 
 If you look in your 1679 Websters Dictionary at the word dragon it says "now rare" 
 
 Marco Polo saw that the Chinese Emperor was raising dragons to pull his chariots, why would he say that? 
 
 Possibly because the was raising dragons to pull his chariots.  (that's my theory) 
 
 So the Dinosaurs/Dragons were Driven off, or Killed off, many ancient recipies call for Dragon bones, Dragon blood, and Dragon saliva.  
 
 So the answer is Humans, they have killed the Dinosaurs.
 
 

The meteor probably. We still do not know for sure, but we can still predict.

dkmec20 : its a meteor you rotten bomb

Most scientists seem to think a meteorite that completely changed the climate is the cause. But that was so long ago; will we really know what happened?

Well it would have to have been a hell of a meteorite...
I mean even if the land was just one continent at the time...
It would still have had to be pretty big...

I say the splitting of the continents.

I am going to have to go with the original theory. An enormous meteor came to earth and landed on the Yucatan peninsula therefore killing all of the dinosaurs. I don't see how one lousy meteor stretches across the entire huge landmasses and kills like 95% of all life. But apparently it starts a chain reaction, when the meteor struck, most plants died, killing the herbivores, and from a lack of them, the carnivores died as well, which I think is weird because they could just live off of all the dead plant eater bodies, but oh well. So I am going to have to go with the meteor theory because it is the most logical reason, and the only one that really seems to make sense that it killed off such a fierce, intelligent species so quickly. It would be interesting if we lived with them, sort of like the show Terra Nova, I always thought that show was kind of cool, too bad it isn't a show anymore. There are so many possible theories debating if the meteor caused climate changes either freezing or burning the dinosaurs from volcanic ash. The meteor's explosion displaced so much ash, killing plants and most of the life, mammals were just starting around that time, and without dinosaurs around to kill them, that's when they started evolving into more complex mammals. Now there are much fewer reptiles, and the crocodile is the only one really closely related to the dinosaurs, due to the fact that they existed with them in the same time period. The meteor killed off about 75% of sea life, because the force of impact of the meteor probably set off earthquakes which triggered massive tsunamis since the oceans were much larger. And most of the birds living in the air died as well from all of the ash that covered out the sun. This is what I believe to have happened.

Lol this is a very interesting thread I will admit. I feel like many things could of caused the 'death' of all dinosaurs. I also feel though everything happens for a reason and this was what was suppose to happen.. me trying to make an image of what it would be like if they were still here frightens me.

Love these type of threads.  I kinda agree with some of the stuff bombchu link said.  I'll just expand on it a bit.  Let's check out the meteorite theory. Theory.  Wikipedia definition of the word "theory" - It is a contemplative and rational type of abstract or generalizing thinking, or the results of such thinking. Depending on the context, the results might for example include generalized explanations of how nature works, or even how divine or metaphysical matters are thought to work.
So in other words - state of mental boredom and unscrupulous amount of thumb sucking leading to revelations of the mysteries of the universe

Did some "research" and this is what I discovered.  The "impact" theory wasn't even formalized that long ago.  It first gained popularity in the 1980s and it came into "existence" as a result of the so-called "K-T extinction event".  Evolutionary geologists calls it an extinction event whenever a number of organisms appear to be missing in a layer of rocks above another layer where they are found.  The most well known extinction event apparently is at the boundary between Cretaceous and Tertiary rocks.  Most of you probably know this, but I had to look it up because I have done this so long ago I couldn't remember anymore, the Cretaceous period - according to evolutionary science - is a period in time, apparently 66 million years ago, where the climate was warm, dinosaurs dominated the land and the sea were populated with all kinds of now extinct marine reptiles and creatures.  Cretaceous is normally abbreviated by the letter "K" for its German translation, Kreide.  The Tertiary period is another "pre-historic" period gazillions of light years ago.  You can look it up on Wikipedia.
Anyway, this boundary between the Cretaceous and Tertiary rocks apparently occurred 65 million years ago on the evolutionary time-scale.  Dinosaurs appear only at the bottom on the Cretaceous side.  Other animal species are not found above this boundary, including many marine reptiles and plants. (unfortunately my link and picture insertion function is broken, so I can't show pictures, sorry)

Luis Alvarez (American experimental physicist and inventor who won the nobel prize for Physics in 1968) and his son Walter Alvarez (a professor in the Earth and Planetary Science department at the University of California, Berkeley) discovered that rocks from this K-T boundary have an unexpectedly high concentration of iridium.  They assumed that this could not have come from earth, because they assumed (again) the earth was originally molten and any iridium would have sunk to the core after millions of years.  They then suggested that this iridium came from an asteroid which fell on the earth.  In 1990 the better "evidence" were apparently discovered for the impact theory.  At Chicxulub, Mexico, formations appeared to be the remnants of a very large asteroid crater.  Such a huge impact would have sent a large dust cloud into the air, blocking sunlight from the earth and causing some species to die out.
The theory however, has some problems - some extremely light-sensitive species in the ocean did survive;  the cloud would cause a long period of extreme cold;  there is too much iridium to fit with the theory.   Asteroids apparently do have iridium in them, but they do not normally spread out the iridium upon impact - areas around impacts are not iridium enriched.  If calculated by evolutionary counting, the iridium would have taken half a million years to cover the earth!  The most likely explanation is that the iridium enrichment came from volcanic activity, not from space.  Volcanoes do produce iridium and it spreads out.  As a result of these and some other problems, evolutionary scientists do not accept the impact theory.

If the impact theory is then not correct, what then?  Some suggested there was a massive drop in our climate and it became very cold.  Others suggested that the dinosaurs ate each other or that they died out from a plague of indigestion ?!
There is another possibility, but it is being ignored in secular science journals and it's the one that makes most sense to me. The impact theory admits the possibility of a global catastrophe resulting from an asteroid or comet, however, the Bible describes a very different global catastrophe that could have caused the K-T extinction event - the world wide flood of Genesis 6 to 9.
The Bible says "all fountains of the great deep were broken up" (Genesis 7:11).  This breakup of the earth's crust would certainly have caused massive and numerous volcanoes during the Flood.  This would explain the iridium in the K-T boundary.  The bulk of the world's fossils would also have formed as a result of this catastrophe.  While pairs of every kind of dinosaur survived the Flood on board of Noah's Ark, it appears that their population never grew large in the new world and finally went extinct.  Just look at today, if it wasn't for zoos and conservation, small populations of other kinds of animals would also (have also) die out.  The cause can be due to various factors: climate changes, diseases, decrease in food supply and of course us humans.

I don't think a Meteor killed them ALL( It is logical though). Because how could one meteor kill them all. I know it was one super continent called Pangea. But I think it has to do with other things starting to become extinct.  They're not like us human they didn't know to watch out and let the small ones reproduce before we kill. I think the big dinosaurs ate the small dinosaurs. The small ones died off, the big dinosaurs had to get food someway, so they started killing themselves for food, they ran out of food, the last dinosaurs only had itself, no food, it died, no more dinosaurs. That's what I think.
