An impact in the asteroid belt might have triggered the Great Ordovician Biodiversity Event on Earth
An article published in the journal “Science Advances” reports a study linking the fragmentation of an asteroid between Mars and Jupiter about 466 million years ago to what is known as the Great Ordovician Biodiversity Event (GOBE). A team of researchers led by geologist Birger Schmitz of Lund University, Sweden, analyzed micrometeorites from that era. The ones of L-type chondrite type that can be linked to the fragments of that asteroid date back to the time of the ice age that marked the beginning of that biodiversity.
