It could have been a double whammy because the radiation would arrive a long time before any particulate matter.

BTW, speaking of South American sabretooths, Smilodon populator was humungous, weighing about half a ton, but the Ngandong tiger might have been even bigger: peerj.com/preprints/2327/ |

I wouldn't want to meet either one in person!  |
