South African scientists found evidence of a hypothesis collisions with the Earth of a comet or asteroid 12.8 thousand years ago. A powerful blow led to climate change on the planet (Dryasian cooling). At that time, many species of animals disappeared. Phys.org reported.

From peat deposits in the South African province of Limpopo rock samples were extracted and thoroughly investigated by scientists. IN samples revealed incredibly high concentrations of platinum, often found in cosmic bodies. This, the researchers say, is a strong enough argument that large a space object (an asteroid or comet) collided with the Earth. Presumably a celestial body fell 12.8 years ago in North Greenland, where scientists discovered a crater with a diameter of 31 km.
If you follow this hypothesis, it becomes logical connection set time of the collision of the celestial body and the onset cooling in the Late Dryas (10 730-9700 BC).
As a result of the impact, soot and dust got into the atmosphere, scattering all over the planet. High concentrations of platinum were found in rock samples in Greenland, Mexico, Eurasia, North America and Chile.
