Scientists Find Evidence of Meteorite Striking Earth 12,800 Years Ago


Our planet, about 4.5 billion years old, has been hit by many asteroids and meteors. These impacting meteors also changed and shaped life on Earth. Scientists have now found new evidence that a platinum-dense meteorite hit Earth 12,800 years ago.

Less than 13,000 years ago, the climate has cooled in many parts of the world, especially in the northern hemisphere. This cooling is known thanks to information from drilled ice cores in Greenland and oceans around the world.

Of course, this cooling gave rise to new effects on the world. Many animals, including mammoths in Europe, big bison in North America, and giant lazy animals in South America, have been extinct.

In 2007 Richard Firestone and other scientists presented a new hypothesis. It was said that this change could be caused by an asteroid or comet. Due to the impact, a large amount of dust may be entrained in the air, which may reduce the amount of sunlight passing through the Earth’s atmosphere. As a result, this may have affected the growth of plants and their animals in the food chain.

This Younger Dryas published a new research on Impact Hypothesis. The research focused on the effect of platinum on this issue.

Where is Platinum in this picture?

Platin is known to be quite dense in meteorites. So if there is too much platinum in one place at the same time, it means that there may be signs of a cosmic collision. Platinum bars were found in the ice core in Greenland, in different parts of Europe, West Asia, North America, and even in South America, Patagonia. It was discovered that all of these belong to the same time period.

So far, there has not been much evidence from Africa. Evidence to support the controversial Younger Dryas Impact Hypothesis was found in his work in the South African city of Limpopo with Francis Thackeray of Witwatersrand University, Professor Louis Scott of Free State University and Philip Pieterse of the University of Johannesburg.

The new information was obtained from the Wonderkrater, an archaeological site with marsh coal. In one example of coal, a platinum rod was found about dust associated with the meteorite that hit the earth 12,800 years ago. The new discovery was completely consistent with Younger Dryas Impact Hypothesis.

Disappearances in Africa

From the South African context, the research team says that platinum-rich cosmic dust and its environmental impact may have a role in the destruction of large grass-eating animals. It is said that three animals, including at least the great buffalo, the big zebra and the big antelope, are extinct in the African sub-continent. These species were 500 kg heavier than their modern counterparts.
