Scientists on Wednesday said dust spawned by a gigantic collision in the asteroid belt between Mars and Jupiter 400 million years earlier triggered an ice age on Earth that ushered in a significant increase in marine biodiversity.
The inner solar system was filled with enormous amounts of dust after an asteroid more than 90 miles in diameter was struck by a smaller object perhaps 12 miles wide, the researchers said. It was the solar system’s largest-known breakup event in the past 2 billion years. Another cooling mechanism was that the iron-rich meteoritic dust fertilized large parts of the ocean surface leading to increased plankton productivity and drawdown of atmospheric carbon dioxide, added Birger Schmitz, a geology professor at Lund University in Sweden and lead author of the research published in the journal Science Advances.
After noting the dinosaur-demise event caused by an asteroid perhaps 6 miles wide, Schmitz added, “For the first time, scientists can now present another example of how an extraterrestrial event formed life on Earth.”
