Did a Giant Comet Kill the Mammoths?
1 Apr
10 — "Some 13,000 years ago the Earth was struck by thousands of
Tunguska-sized cometary fragments over the course
Though the earth had been warming since the end of the last ice The cooling lasted more than a thousand years, and its onset coincided with the rapid extinction of 35 genera of large North American mammals, as well as the disappearance of the Clovis culture.
The
occurrence is marked by a black mat a few centimeters thick found at
many sites across the United States.
The
catastrophe was caused by an extraordinary extraterrestrial Professor Napier proposes that the Earth ran into a dense swarm of material from a large disintegrating comet. According to Napier, the encounter would have lasted about an hour, during which thousands of impacts took place. Each impact released the energy of a megaton-class nuclear bomb and generated the extensive wildfires, says Napier. The nanodiamonds would have come in on the comet.
