It wasn't that long ago when talking about even one meteorite was controversial. BBC:
The dinosaurs were wiped out 65 million years ago by at least two meteorite impacts, rather than a single strike, a new study suggests.
Previously, scientists had identified a huge impact crater in the Gulf of Mexico as the event that spelled doom for the dinosaurs.
Now evidence for a second impact in the Ukraine has been uncovered.
This raises the possibility that the Earth may have been bombarded by a whole shower of meteorites.
