Debate: Extinction of Dinosaurs

[_Roxas_]

~~~~After some Debate about God, it went off to going to the extinction of Dinosaurs. I think that global warming had it's effect, weather and floods caysed the Dinosaurs to die and be the main cause for their death. SOme thing the "Big Bang" was the reason. BB had nothing to do with Dinos. It was the reason the universe was made. So now it all rests.... what do you think is the real cause? And please be specific and truthful ^^ if this thread has been already made, please close this.

'Kay so, if my Big Bang thread was deleted, I think this one should be aswell...
It is pretty much being debated in the other thread.

[_Roxas_]

Whoops. Then a Mod can please close this.

[The King of KH]

PM a Mod............cuz i dont think they will get this

[The Real keyblade Master]

No!

This is a resonable thread and shouldnt be closed.

Its about the extinction of Dinosaurs.

[The King of KH]

No!

This is a resonable thread and shouldnt be closed.

Its about the extinction of Dinosaurs.

It depends on what Roxas wants to do.............

[The Real keyblade Master]

The other dudes just mad.

by far the most logical theory is that a meteor or somthing (i forget the name) hit the earth with incredible destructive power
predictions say it wouldve been 6 miles wide in order to cover the whole planet in destruction
these things tend to be full of liquids which mix together wen the meteor hits earth and cause a destructive power which humans have never actualy witnessed
the reason people think this, is because when digging dinosaur bones they found a thin layer of rock and metal which is only found on other planets to earth and INSIDE METEORS
the fact it was so thin suggests it was only present for a short time
this theroy works on other levels too
the way life continued after the damage is quite typical
life is destroyed in mass amounts but always returns in a new evolutionary form
new plants came into exsistance but old ones survived
alot of sea dweling animals survived: sharks, crocidiles, alligators
its by far the best theroy on the market

So true. I don't think that anything other than a meteor or a comet could have caused the mass extinction. Since the dinosaurs were definitely wiped out by a cataclysmic event, we could run through the possibilities:
Supervolcano-Well, very interesting, but they haven't found a layer of volcanic ash along with the dinosaurs.
Major Earthquake-Well, must have been one hell of an earthquake to cause a mass extinction. The problem is that a major earthquake, if over the ocean, would have caused a tsunami and supervolcano eruptions, which was disproved earlier. Overland wouldn't do that much.
Global Warming-I'm not sure how this fits in, because this theory doesn't explain the layer of sediment that accompanies dinosaur fossils.
Comet/Meteor Impact-I think it's the most likely. A rather huge crater can be found in the Yucutan Peninsula, Mexico, which would indicate a meteor hitting the Earth at some time. Since the crater is now an ecosystem, that would indicate a long many years so that lifeforms could thrive there. Like robbie said, the layer of sediment discovered also matches up with that theory, and the impact made the temperature of the Earth to pretty much roasting levels, and a quick global cooling followed that.

I believe that the great flood in the Bible was the cause of the extinction of the dinosaurs. The dinosaurs were wiped out except for the ones taken on the ark as the Bible says that some of every animal were taken on the ark. I believe that when the dinosaurs got off the ark there was not enough food for them as there were alot less animals now since most had been wiped out except the ones on the ark and that they went extinct because of it. Or maybe some other change after the flood caused them to go extinct but I believe the flood was the main cause of the extinction.

[Shadow's Destiny 42]

I don't kniw why you have the Big Bang on their...
The Big Bang was the very start of the multi-verse and the start of time itself.
Life didn't even start 'til millions of years later.

supervolcano's and earthquakes are very much out of the equation as they can only occur where plate's meet which is only a small area
hence why most of europe never have volcanos or earthquakes
so this could never produce enough destruction for mass extiction
global warming can only wipe things out with the help of human pollution
and even then its only arctic life that will be wiped out and only certain area's will be submerged by the rising sea levels
and dinosaurs didnt live like we did
global warming is a natural occurance
but thanks to us humans and our fossil fuel machines we're making the effects alot more potent hence the danger
global warming could never have caused mass extiction and never will
the meteor theroy also works cus it gives reason for the ice age
wen the meteor hit it would've caused huge clowds of debrey and ash just like volcano's do but one a much much much bigger scale
and when this happens all over the globe the sun gets blocked out
without any sunlight the planet freezes and turns into a great ball of ice
this then makes all life, animal and plant,evolve to survive this new habitat which also adds to the theroy because it shows how dramitcally life on earth changed after the impact

this makes little sense
its a well known fact that humans and dinosaurs never co exsisted
plainly because if they did humans would've been wiped out
wen humans were evolving they were generally surrounded by herbivores so they could live in relative safety and evolve into somthing dangerous
back then humans were not as dangerous as they are today
so if the dinosaurs had been living with them, there is no chance of survival
dinosaurs were the ultimate in natures creations hence why it took such cataclysmic events to kill them off and thats also why they were so cataclymic, because the dinosaurs were so good at survival
plus the great flood does not include the incredible change of life made after the ending of the dinosaurs
a flood could never do so much damage or make evolution take such a turn
its the reason humans exsist in the first place
a flood could never cause somthing so great
plus if dinosaurs and humans lived together how come their bones are found in completely different time zones
im talkin million of years apart

A small area doesn't mean a small impact. A supervolcano literally could cause as much trouble as a meteor impact. Considering that there definitely is a possibilities of multiple lava pools in an area, and the possibility of a chain reaction through the earthquakes, it is slightly conceivable. I mean, the chances of that happening is just about the same as the same size meteor that wiped out the dinosaurs could hit us.
Europe has volcanos... Remember Pompeii? But the reason is because the plate tectonics of that area generally doesn't allow for those things to occur. The Ring of Fire on the other hand... That might be totally different XD. But then again, there is no evidence of volcanic ash with the dinosaurs so...

I have to disagree. Global warming can cause mass extinctions and wipe things out without us. Fossils fuels actually don't contribute too much to global warming. In fact, our breeding of cows actually contribute just as much to global warming as us. The thing is that as global warming increases, the oceans can absorb more carbon dioxide, though most plants tend to favor photorespiration, which uses up oxygen. Anyway, that's getting too technical.
You mentioned arctic life that will be wiped out and how global warming could never have caused mass extinctions. Kind of contradicting :p.

True, and true. Although the fault in that explanation is that 'all life evolves'. Not really. Animals and plants cannot evolve in a week or two. Rather, the concept of natural selection, also known as 'survival of the fittest' comes into play. Large cold blooded like dinosaurs are hardly able to survive in such conditions, thus they probably died in the week or two in which the earth was frozen. Rodents, cold surviving plants, those that had seeds deep underground, cold blooded animals that could burrow, all those have survived because they were already adapted to survive. Early primates could have found shelter or something. Regardless, the phylums that survive today found some way to survive such a catastrophe.

True, true. The fact of the matter is that early boat building techniques could not have built an ark of such a size that it wouldn't capsize on itself or just break apart. Plus, there is no conceivable source for that much rain to suddenly appear. The ocean? Then the earth must have been just a little bit closer to the sun... But that can't happen because water can't exist at such temperatures. Another problem would be that the cold blooded reptiles would conceivably have died due to lack of heat. A fire on a wooden boat... Probably not a good idea either.

1.super volcanoes, did not know that, thanks for the intel

2.wheaver or not fossil fuels or cattle methain causes global warming more is not important
and that statement was only a cantradiction because of bad termanology
yes it'll kill arctic life but thats it
simple and easy mistake
dont split hairs about it :p
the only other life on earth that is affected by global warming is sea life who can get confused by new temperatures in the sea when migrating to warmer climates

3.all life does evolve
i know it dosnt take weeks it takes millions (possible billions) of years
but as long as plant or animal is in a habitat their not suited for, evolution will run its course
and goin bak to the theory of the meteor itself
the theory is that all life reverted back to how it once began with small hints to how life once was
hence why birds and modern lizards are so like dinosaurs
mammals survived proceeded to dominate the earth
and so on and so forth
as for the speices that survived
most of them are water dwelling or amphibious
when things like this happen the sea or any large body of water is always a safe spot
hence why our oceans reamin such a spectacualr natural wonder
its the only place on earth not have faced mass extinction
this is why crocodiles and sharks survived
as for any other survivors im not too sure cus i dont really know of any others

1. We all learn things :D

2. Well, it won't only kill arctic life, but it will kill many creatures living on the chaparral areas of the world (also known as the area near/around the coast). Not only that, but warmer temperatures might cause heat waves which could cause mass extinctions if they last long enough. However, that's actually moreso in the future, but it's a possibility. Sea life might not be affected that much, since I don't think we're quite sure exactly how sea creatures detect when/where to migrate.

3. Well, that depends. If the initial animals were killed in the first place, then there's no chance for evolution (well, kind of obvious).
They're not just like dinosaurs, but they certainly evolved from them because we can see homologous organs and body parts.
The oceans are not impervious to extinction. The heat wave could have killed surface organisms. The ash thrown up after that would have killed all photoplankton. Then, all subsequent organisms would have died. The only organisms able to survive would have been bottom dwellers because of chemosynthesis by bacteria. Then as the light returned, life migrated up again. And then evolved. After all, life had 65 million years to evolve.

*Note* I haven't read much of what you guys have written so far. Too many words. I'm just giving you that random comment that makes you chuckle (hopefully)


Maybe life is actually like the Hitchhiker's Guide to the Galaxy and that the Magratheans put the Dinosaur bones for human's to find and think they existed.
