[math-fun] Dinos died from 2nd hand smoke

Is that a stone-age bike shed they're lurking behind? WFL On 7/15/16, Marc LeBrun <mlb@well.com> wrote:

"So how did birds survive?" Excellent question! Most scientists think that the primary victims were *large* animals, with the possible exception of large animals living in the oceans. There remained plenty of oxygen in the atmosphere, but also lots of possibly poisonous gasses. Smaller animals in burrows might have avoided some of the worst fire conditions in the aftermath of an asteroid hit. We now (post-GPS) know that some birds -- even some very small birds -- can migrate prodigious distances (thousands of miles), in which case birds may have survived on far-flung islands. I don't know how many burrowing birds there are. At 08:15 AM 7/16/2016, Mike Speciner wrote:
