Laelaps on the Carboniferous Atmosphere

In many a time-travel story, little attention is paid to the local ecology of the destination of the intrepid travelers. If you’re headed back to visit Leonardo da Vinci, this probably isn’t going to be a problem, but if you’re headed back much further, like the Carboniferous or Permian, you might run into some trouble. Indeed, nothing could kill such a “time safari” quicker (like the one in L. Sprauge de Camp’s “Crocamander Quest,” collected in The Ultimate Dinosaur) than stepping out of the time portal/capsule and not being able to breathe. Fanciful notions of time travel aside, we can tell something about the ancient atmosphere without having to actually step foot there, and it has some very interesting implications for evolution and ecology.


A very good post. I recommend reading it.
