I've been watching a series called Animal Armageddon

http://en.wikipedia.org/wiki/Animal_Armageddon

The episode I watched this evening was "Strangled", in part about
a previous eruption of the Yellowstone Caldera

It is chilling to see how a roll of the survival dice determines whether
a species lives through a cataclysm, and how close our distant
ancestors, and we, may have come to not being here. The way that
the series' CGI recreates these extinction events gives you some
idea of the inescapable global impact
