What other theories are there for the extinction of the dinosaurs?
Hi i was just wondering if much thought has been given to whether if an asteroid hit earth causing dinosaur extinction, why would ALL the sealife die out also? how about dinosaurs( i know im using wro...

What are the theories for the extinction of the dinosaurs, other than the meteorite?

Woolly mammoths died out because of dwindling grasslands - rather than being hunted to extinction by humans, according to a Durham University study.

what is the reason for extinction of t-rex dinosaur?
I saw a report on Teletext suggesting an alternative theory for the extinction of the dinosaurs. Suggested that the plant eaters ate so much foliage that they broke wind continuously. The result was d...
Hi all,
I recently watched a documentary on the new theory of the mass extinction 13,000 years ago.
The new theory suggests that a meteorite impacted into the North American Ice Sheet,hence why ther...
... theory that a large bolide collision was responsible for the dinosaurs' (and many other organisms' extinction.
What is it, specifically, that you think is wrong with this theory?

If there were multiple meteor strikes, then how come the K-T Extinction wasn't the biggest in history? That title belongs to the Permian extinction, which was caused by climate change, as Pangaea...
...eous. But as they point out, the fossil record does not support their hypothesis. They also argue that a mass extinction of birds at the K-T boundary would mean that 'most modern bird orders with...
Hmmm,
They discussed the extinction of the Moa, the giant marsupials, birds and horned tortoises of Australia, and the giant lemurs from Madagascar (yeah, I know! Marsupials and lemurs are mammals...

G'Day,
What you are overlooking is the so-called 'Broiler Effect', the radiant heating of the earth's surface caused by the massed reentry of a vast quantity ...

If you are referring to the Permian Extinction, which wiped out almost 95% of all life on Earth, these are some of the many species that died.

Hi
Do you think the causes for the extinction of non avian dinosaurs differed from the reasons for the extinction of avian dinosaurs?
I can't see why it would be this way, but have heard some p...
... This indicates that a meteor hit the Earth 65 million years ago somewhere in Central America causing the K-T Extinction. There is evidence to support that. The mass extinciton seems to have been caus...
And yes, I do know that the events prior to the Cretaceous-Tertiary extinction event caused more herbivores to die, but it also had its effects on T. Rex, as well. In fact, you would probably be lucky...
May I suggest the following article which summarises the arguments for volcanic theory of mass extinction at K-T boundary. It also includes a list of flood basalt eruptions and their correlation with ...
...le to tell because it depends on how long before speciation occurs and the environment is consantly changing. Extinction doesn't necessarily mean death. It really means the disappearance of all i...
: extinction debate, for example in the ammonite data, more thorough data : collection did show that extinction was rather abrupt at the K/T boudary, not : occurring far in advance as some had maintai...
How many times will I have to explain this. An impact induced extinction event would result in animals starving to death from lack of plants because the plants have mostly all died from lack of sunlig...
I always wonder why people search for a single, primary cause for an extinction, especially the KT extinction. It is almost certain that an asteroid or comet impact had immense environmental impacts u...
Extinction is caused by species killing or causing death of more than it really needs. Basicly animals can also cause their own extinction. Lions are protective of their pride, but if they kill more ...

The slow-extinction and fast-extinction hypotheses don't necessarily contradict, you know. There could have been a long, slow change in the atmospheric composition and climate, which reduced the ...
