The anomalous platinum trace in North America has just reinforced the existence of a cosmic object believed to have caused the last ice age and the tragedy of extinction.
Scientists from the University of South Carolina (USA) have discovered something special they call "platinum spines" that are mixed in sediments at White Pond, South Carolina. "Platinum hemp" is an unusual form of platinum , involving cosmic objects such as comets, asteroids and other meteorites.

The new discovery strengthens the puzzle piece of platinum anomalies dating from this research group in many parts of the world, including other parts of North America, Europe, Western Asia, Chile, and the South. Africa.
All of this evidence has revealed a space object, possibly an asteroid that plunged into Earth or a large comet exploding in the sky 12,800 years ago. At the same time, traces of the globe show that it is a global event, not encapsulated in North America as previously thought.
The beautiful-named event of a flower - Younger Dryas - created dust clouds covering the earth, blocking sunlight and creating an ice age lasting 1,400 years. This difficult period led to the extinction of mammoths, saber-toothed tigers, mastodon elephants, giant sloths . and a variety of carving creatures.
The event also coincided with a period of severe decline in human populations, which the archaeological evidence of Clovis culture in the Americas has most clearly demonstrated. Thankfully, humanity can still survive and restore populations at last.
Earlier, a suspected trace of a crater with high concentrations of platinum and iridium was discovered near Greenland Island - the icy Arctic island. The effects of the same kind have been shown to shoot many rare elements and even "glass meteorite" particles scattered around the Earth.
The research has just been published in Scientific Reports , an edition of the journal Nature.
