Diamond clues to beasts' disappearance? 2 Jan 09 "We've discovered nano-diamonds that are not normally produced through average processes on the surface of the Earth," said James Kennett, a geologist at the University of California, Santa Barbara. "They indicate there was an extra-terrestrial event on Earth 12,900 years ago," he told BBC News. The nano-diamonds coincide with the onset of cooling, says this BBC article, and may have wiped out woolly mammoths and the Clovis culture in North America. The age of these materials coincides with the start of a millennium-long climate cooling event known as the Younger Dryas. The sheer number of diamonds - up
to a million times that found in neighbouring sediment - and their
presence inside spherules, refutes the speculation that the material is
the normal rain of meteorite debris, says Allen West, a retired
geophysicist in Arizona and a co-author. The absence of some traditional impact material and visible craters in North America led researchers to speculate that a meteoroid or comet disintegrated before exploding in a cluster of airbursts. The thumb width layer of diamonds, which lies beneath a black mat of carbon, appears in a number of sites across North America including Murray Springs in Arizona and the Channel Islands off the coast of Southern California. No skeleton of one of the larger (now extinct) ice-age mammals, or a Clovis artifact, has been found above the impact layer or the black mat, said University of Oregon geo-archaeologist Doug Kennett, son of James Kennett and another author on the Science paper, who has studied sedimentary vegetation and charcoal records. The sky would be a canopy of fire, said Dr. West, and shock waves would flatten trees. Miniscule diamonds would drizzle over tens of thousands of kilometres, a third of the way around the planet.
