Could a geomagnetic reversal be the cause of the dinosaur extinction?

Question

Geomagnetic reversals are explained here...

http://en.wikipedia.org/wiki/Geomagnetic_reversal

Answer 1

Absolutely not.

There was only one dinosaur extinction, and about 7 or 8 other extinctions on a similar scale, at approximate intervals of 64 million years.

There have been many geomagnetic reversals, at irregular intervals as short as 50 thousand years or as long as several million years.

So the two types of event simply do not match up.

Answer 2

No, but a geomagnetic reversal could be the result of a common cause, the presumed meteor impact which caused the extinction, 65 million years ago.

Answer 3

We did not record such reversal yet (at least strong enough to really influence life on earth). We are capable to follow the fluctuation of the geomagnetic field trough geological layers and date them, and none of those occurence has been proved to have caused mass extinction...

Answer 4

I don't know about dinosaur extinction, but was told by a geography teacher in Canada that somewhere in northern Canada, Northern Territories or something, they had discovered a fossilised coral reef. The really interesting thing is that the living coral reef apparently grows along the magnetic fields of the earth, that is, from North to South, but this ancient, fossilised reef had grown from West to East, indicating a magnetic shift had occurred causing it to grow in that direction, or should I say a shift occurred which has caused today's coral reefs to grow in the opposite direction 90 Degrees from the original direction.

Answer 5

no, because they could prove that by matching when magnetic polarity switched to various mass extinctions, both are tracable in the rocks and they do not match.

Some species would suffer, like pigeons which use magneticism to navigate (I know pidgeons did not exist back then). But other than that not much else would be affected.

The earth magnetism does protect us from lots of harmful suns rays which are directed to the poles, hence the northern and southern lights, so a switch could temporarlily halt this and we would get serious radiation!!!

Answer 6

One big meteor falled to Earth , nearby Gulf of Mexico causing a great unstability on weather to begins a long winter. causing dinosaurs extinction, cientists prouve that observing layers of ground dust, found on eternal Iced surface of poles, in fact the recentely change on geomagnetic inclination on Earth could be caused by this same BIG EXPLOSION (they also says that Norway coast would be more iced on that time due observing today the fjords ).

Answer 7

Yes, I think this might be one of the possible theories of what caused the major cataclysms on Earth that might have led to the extinction of dinosaurs. Periodically, Earth's magnetic field reverses.

Answer 8

The theories on what the impact on pole reversal would do is quite unsettled and is unknown at this time as to what could happen. There are theories ranging from mild to extreme changes. So it is possible but personally, I think unlikely.

Answer 9

well yer because there PlayStation's would not work so they all got angry and beat each other to death.
