Sophisticated hunters not to blame for driving mammoths to extinction
Guardian ^ | Thursday, November 19, 2009 | Ian Sample

The animals, which included mammoths, elephant-sized mastodons and beavers the size of black bears, were probably picked off by more inept hunters who only much later developed specialised weapons when their prize catches became scarce. "Some people thought humans arrived and decimated the populations of these animals in a few hundred years, but what we've found is not consistent with that rapid 'blitzkrieg' overkill of large animals," said Jacquelyn Gill, a PhD student at the University of Wisconsin, Madison, who led the research team... Gill's team rules this out by putting a more accurate date on the decline and fall of woolly mammoths and more than 30 other large mammals that dominated the landscape as the ice sheets retreated from North America. Among them were giant sloths the size of SUVs. To date the animals' slide to extinction, the scientists examined sediment cores from a lake in Indiana. The deepest sediments were laid down in the distant past, while more recent sediments were nearer the surface. Specifically, the scientists measured levels of a fungus that is known to thrive in the excrement of giant herbivorous mammals and nowhere else. They reasoned that more fungal spores meant more dung, which in turn reflected a larger population of roaming mammals. The sediments also held ancient pollen and charcoal dust, which gave the team clues about the predominant plant life and frequency of wildfires. Writing the US journal Science, the researchers describe how the amount of mammal dung started to fall around 14,800 years ago, long before advanced spearheads became commonplace. The animals had been almost completely wiped out a thousand years later.

It's one of those "anything but accept the reality of large scale catastrophe and its role in mass extinction" papers. :')

I thought that they found a whole layer of nanodiamonds and no skeletons of mammoths appeared above that layer. And that the ones that did appear in that layer showed signs of pitted tusks from debris.

That's what the history channel said, at least.

This is silly. Everyone knows that George W. Bush personally went back in time and savagely killed all of the mammoths personally.

The thing that interests me about extinctions is how they might actually be caused by a combination of events. Populations will survive environmental catastrophe several times only to disappear because the thin edge of survival gets tipped somehow. Sometimes what seems insignificant gets over looked in theories. For example lets say one little hunter has a rare talent for hunting mammoths, a rock slide blocks a critical mountain pass, or a virus hits at the same time as another environmental stress. How often are things happening even today clear cut and not influenced by multiple factors.

It was the south Texas BBQ crowd that did it.

:’) Mammoths croaked off, here and there, throughout their time on the Earth, just like every other creature. What this “study” says is that the group involved is applying the local climate around a lake in Indiana to the entire continent (among other assumptions). As you said, there aren’t any mammoth kills in North America antedating the black mat, and there aren’t any Clovis artifacts that antedate it, either. Whatever and whoever made the Clovis artifacts were wiped out (or nearly so) by the same event.

"were probably picked off by more inept hunters"

That's depressing...not only to be slaughtered, but to be exterminated by the inept.
