Overhunting. Abrupt climate change. Disease.

Scientists have cited those and other theories in their decades-old debate about why mammoths, mastodons, sloths, saber-toothed cats, camels, horses and other large creatures disappeared from North America at the end of the last ice age.

now a research group that includes two University of Oregon scientists is proposing a more dramatic cause for the extinctions: A 3-mile-wide comet or asteroid exploded over Canada or slammed into the continent about 13,000 years ago.
The researchers say the impact also may have wiped out or fragmented the prehistoric Clovis people who flourished in North America at the time.

Michael Hansen, a geologist with the Ohio Geological Survey, said, "We have many sites in Ohio where we have found ice-age animals that are much younger than that."



Dale Gnidovec, curator of the Orton Geological Museum at Ohio State University, said, "It's a neat theory, but so far I haven't seen a lot of ironclad evidence."



Bradley Lepper, an archaeologist for the Ohio Historical Society, said, "The theorists have some interesting data, and it makes you want to believe. Just because of that we have to be skeptical.

"The Clovis smoothly transitioned into other cultures," he pointed out. "Out on the Plains, it changed into the Folsom culture.



I can't wait for pseudo historians to enter this one and claim it was a high yield nuke that did the damage as has been proven already because it was mentioned in numerous ancient texts.

I believe this is the basis of Scott Creighton's idea. He seems to think this comet took out Atlantis, and the Atlanteans left a design for the Egyptians to follow and who then built the pyramids to said plan to let us all know about it.....

It's possible there was an impact in N America around that time. No reason for thinking it selectively wiped out several species though.

Still not got around to reading Firestone etal's book properly yet. But like all such catastrophist theories they seem to be trying to pin everything onto their pet theory, rather than accepting that different events in different places at different times were all involved .....

After all, it's like finding evidence in 10,000 years time of the Tunguska meteorite/comet and assuming it was responsible for the extinction of the auroch, European lion, dodo, tiger, the destruction by fire of Dresden, and the legend of Harry Potter and his flying broomstick ......

I found the book The Cycle of Cosmic Catastrophes to be repetitive and like you said, guility of overstating the theory that one thing did all the bad stuff at the end of the ice age era. People forget that the mega fauna of North America was not the only ones to disappear, they disappeared across the entire global with only a few examples surviving in Africa.

I think in 15-25 years more information will show that there was one or more asteriod/meteorite hits that contributed x amount of blame for effects z and y.

Wow... I got about half way through and decided to look up some of this stuff and when I did I found an intresting theory on how life started on earth... I'm going to post a topic about it later...

As others have stated it doesnt explain the extinction of megafauna from around the world.
Lots of theory's here for the extinction of Australian Megafauna but no solid evidence for any of them.

Something happened to thin and ultimately wipe out a great deal of the megafauna in the world.

The last Mammoths survived on Wrangel Island, Arctic Ocean, until around 2000 BC.

Its a mystery, I suspect, weather, disease, predators (of their young), humans, loss of food resources and genetic problems.

I believe also that we'll find that surviving populations existed in pockets like the mammoths of Wrangel island.

Hello Hans,


Hans: I believe this is the basis of Scott Creighton's idea. He seems to think this comet took out Atlantis, and the Atlanteans left a design for the Egyptians to follow and who then built the pyramids to said plan to let us all know about it....


SC: I believe the term I use is 'Lost Civilisation'.

Regards,

SC

ok so you aren't saying the "A" word Scott
so which lost civilisation was it ?

The comet may have been responsible for much more than the extinctions mentioned. The Laurentide ice sheet was several miles thick and covered a vast area of North America. An airburst of this magnitude could have melted hundreds of cubic miles of ice more or less instantly. In the process, it would have vaporized cubic miles of melt water super-saturating the Earth’s atmosphere. The ice sheet was thousands of feet in height. The out-rush of water from the former ice sheet would have created a mega flash flood of vast height and proportion. In many areas it could have been well over a thousand feet in height and hundreds of miles wide. As the mega flood rushed from the Colorado Plateau to the Gulf of Mexico, it would have carved out hundreds of miles of landscape in a short time span and on an unbelievable scale. This could account for many of the spectacular canyons, mesas and other land formations now visible in the American Southwest.
As hundreds of cubic miles of run-off reached the Gulf of Mexico, it would have combined with the torrential global rainfall, causing sea levels to rapidly rise hundreds of feet world wide. For those who entertain such ideas, this could also account for Plato’s legend of Atlantis. Plato wrote that Atlantis sunk into the sea during a day and a night of unbelievably torrential rainfall. Coincidentally, Plato places this event at about 10,500 B.C. What might have actually happened was that the super saturated atmosphere released it’s water vapor within a time span as short as a day or two creating unprecedented epic level rainfall around the globe. This combined with the cubic miles of run-off from the Laurentide Ice Sheet, causing global sea levels to rise suddenly. To the survivors of Atlantis the rising sea level would be experienced as their island sinking into the sea. It would have been impossible for them to distinguish between the two scenarios.
Mega event theories have, until the last few years, been viewed with disdain by the scientific community. Now, however, many such mega events have come to light and are universally accepted by mainstream science. Events such as the Montana scablands mega flood (over 1000 feet high), the catastrophic flooding of the Black Sea the south-east Asian super volcano about 70,000 years ago that wiped out about 99% of the human gene pool and many others.
We now know that the slow and gradual processes, that we previously thought shaped the Earth alone, have been punctuated again and again by many mega events of unimaginable proportions.
