It will be interesting to see if the evidence sticks for a comet causing
the demise of the big North-American mammals and possibly also setting
of the Younger Dryas event.
When in doubt, invoke catastrophic celestial events. In this case they leave
only the most elusive evidence.

Any invocation of catastrophic events can be handwaved into doing the exact
amount of damage desired and no more.

True large mammals in the higher latitudes but also in the not so high
latitudes but not close to the equator. The ice age returned for a short time?
But the mammoths were in the higher latitudes during the ice age. There were
fires? One expects a layer of carbon at the same level as these diamonds. One
also expects the most fires in the region with the greatest vegetation, the
tropics. But that is exactly where the elephants and other large mammals did
survive. So this catastrophe targeted exactly what disappeared in the places
where they disappeared. Ad hoc does not make for a robust theory.

This is a funny post. The camels, hippos, horses, etc went extinct
640,000 years ago as the digs in Nebraska prove. The Yellowstone
cauldra erupted and wiped out a large part of the animal population.
Nothing shows up from 13,000 years ago except modern humans which
killed off everything they saw. Who would present something like that
and expect to be take seriously? K.W.

The New Scientist takes it seriously. A two page article today arguing that the comet was the cause of the Younger Dryas.

And the AGU meeting devoted three sessions to it. The two I missed are http://www.agu.org/meetings/sm07/sm07-sessions/sm07_PP41A.html and http://www.agu.org/meetings/sm07/sm07-sessions/sm07_PP42A.html
