Makes more sense than claims early man hunted them to extinction with spears and clubs.

Personally I think they watched too much hockey and just faded away...

From Richard Cronin:

The extinction of large mammals such as mammoths and sabre tooth tigers took place in a very narrow time frame. Robert J. Tuttle ("The Fourth Source. Effects of Natural Nuclear Reactors”) hypothesizes that a large comet or several comets of frozen methane and ammonia exploded and fragmented across the Northern Hemisphere. The effect would be like flash freezing as the frozen gases immediately vaporized. Large mammals caught in the open in lowlands would be most susceptible.

As evidence, he points to discoveries of fully intact mammoths found buried in the tundra of Siberia. They died with stiffies caused by the immediate suffocation. Kinda like sado-masochisti c practices.

Sounds more reasonable than a few ppm of CO2.
