Then why did they go extinct?

  Due to a gigantic asteroid strike. Interestingly, crocodiles, which are cold blooded creatures, survived OK.

    This article doesn't make the connection, but it's an interesting hypothesis to assume that all cold blooded creatures that were big couldn't maintain their body temperature after a drop in temperature from a comet impact, but that creatures that were small already were better in coping with fluctuations because of their smaller size.

      It's more likely that large creatures couldn't get enough food, because sunlight was blocked by dust clouds and a lot of plant life died as well. The percentage of Oxygen on the atmosphere might also have been affected, making large lifeforms unable to function efficiently enough.

      The thought the latest theory was the entire earth was engulfed in flames from the impact and killed almost everything except stuff underground / underwater http://www.radiolab.org/story/dinopocalypse/ http://www.radiolab.org/story/dinopocalypse/

        I didn't listen to this audio, but if this were true, shouldn't geologist have already discovered a layer of ashes spanning the whole world?
