Apparently, it wasn't an asteroid that killed the dinosaurs.

Well there is "evidence" to support the asteroid argument, eitherway there was a heavy layer of dust that settled on the earth 65 million years ago when the dinosaurs disapeared.

Not gonna look it up again, but I remember reading about "super volcanos". The entire Yellowstone area is a giant crater.

Either way, God must have hated the dinosaurs... Repent! Lest I smite thee! ;)
-
WHAT!!!
it was actually caused by us humans using them as cranes and such:lol

LMAO Vort

EEET EEES FAULT OF GREAT SATAN BOOSH! DETH TO AMREEKA!

The entire Yellowstone area is another super volcano. :eek:

This theory, already supported by a significant body of geologists and palaeontologists, is strengthened by new evidence to be presented at an international conference at Cardiff University on 11-12 September.
sorry they have used the word "theory" wrong. in science a theory is a idea shall we say that has been proven through expirmentation.:D (im so smart) which this hasn't so i stoped reading there.

So the crater covering part of the Yucatan and the Gulf of Mexico fits into this theory how?

In my opinion, all dinosaur "sudden extinction" hypothesi (sae?) contain at least one major flaw.
There was a huge variety of Dinosaurs - in all sizes, from tiny to huge, carnivorous, herbivorous, omnivorous, land-dwelling, water-dwelling and amphibious.
I understand that sudden climate change or development of poisonous alcaloids by grass could have killed the huge dinosaurs quick. But what about the small ones?
How come the same size mammals, reptiles, insects and other kinds survived in the same locations while the dinosaurs completely perished in a short period of time?
The only thing that seems to me capable of such quick and complete devastation is biological - some virulent virus or germ combined with some defect in their immune system or genetic suseptibility that did not affect mammals/insects the same way - or maybe even was spread and supported by them.
If that bug affected some major biological mechanism common to all dinosaurs that could not be evolved out and/or was stable in soil for a long time or spread by other species, all the dinosaurs would die. For all we know, it could have been measles or common cold.
Just imagine a bug affecting humans with spore stability of anthrax, water-bournness(?) of dysinthery, virulence of ebola and spreadability of common cold.
One could such bug would quickly kill all of its own carriers just like ebola and there would remain pockets of humanity not affected - but imagine it could be spread by mice, birds and moskitoes without killing them?
So far bugs evolved resistant to all the new drigs we could come up with. Of course our immine system is very advanced and second in complexity only to brain, but in a period of millions of years something is bound to come up that will find a chink...

The Cretaceous/Tertiary (K/T) extinction did not affect dinosaurs only. In fact, about 20-25% of all species, including plants and protozoa, were wiped out.
And this extinction was relatively mild compared to some. For example, the late Permian extinction affected about 95% of all species.

myelo: The Cretaceous/Tertiary (K/T) extinction did not affect dinosaurs only. In fact, about 20-25% of all species, including plants and protozoa, were wiped out.
We are speculating about some deadly primary cause here.
Minor fraction of those 25% of species, dinosaurs among them, could have been killed totally by the whatever primary cause.
Most other co-extinct species could have been partially or not at all affected by the same phenomena but went extinct because of disruptions of their food chain or lifesycle.
Like those evolved to eat dinosaurs or dinosaur dung, or have seeds trasfered by dinosaurs or parasytise on dinosaurs.

Dinosaurs killed by virulent disease?
And here we are displaying their bones out in the open! Who's going to protect the children!

As I've said - if that was a desease and it still exists - not necessarily in a 65-million year old bones - it may be some common bug harmless to us like flu or even a beneficial symbiont - like e-coli that protects us from colon cancer, etc.
Remember - 95% of the native americans (19 out of 20) died within a few years of the contact with Europeans, reducing ~100 million population to about $5 mil practically overnight. It took them about 200 years to get their numbers to about 14 mil and they were still plaqued by deadly epidemics. That kind of mortality rate is very close to extinction and we talking about a deseases that already were prevalent in humans - meaning its virulence was reduced by natural selection to sustainable levels and to which at least some fraction of humans had resistance in the first place.
Even now whenever researchers make contact with an undiscovered tribe in Amazon Basin, over half of them die within months from the common flu.
A bug jumping from another species or a newly evolved variety to which no one has resistance but which can be spread by other species and so is not self-eliminating could certainly wreak havoc with any related set of species.
