According to researchers, a comet struck the ground or exploded over North America 12,900 years ago.: (CNN) -- Tiny diamonds found in the soil are "strong evidence" a comet exploded on or above North America nearly 13,000 years ago, leading to the extinction of dozens of mammal species, according to a study.
Diamonds found in North American soil suggest a comet led to the extinction of dozens of mammal species.
The scientific report also suggests the cataclysm also reduced the population of the earliest people to inhabit the region and triggered a 1,300-year-long cold spell that stretched around the world.
The heat generated by the extraterrestrial impact likely melted much of a glacier that once covered the Great Lakes region, sending a massive flood down the Mississippi River, the study said.
According to the report, the cold waves of glacial runoff into the Gulf of Mexico shifted Atlantic Ocean currents, changing climate patterns throughout the world in a cooling period known as the Younger Dryas. |
Nanodiamonds found in the strata associated with the "Younger Dryas Boundary" in at least one case lie directly on top of a Clovis (paleoindian) culture site. The researcher conclude that the cometary impact caused the extinction of much North American fauna, loss of Native American population, and major world-wide cooling.
(Most interesting to me, all this took place thousands of years before the earth was created.)
