  • New evidence: Asteroid's 'bad timing' killed off dinosaurs
    2014-07-28 05:24:16 UTC

    Dinosaurs might have survived the catastrophic impact that ended their reign had the devastating asteroid that slammed into the Earth arrived at a "more convenient time", a scientist has claimed. As a result humans would probably not exist. The violent collision 66m years ago, which occurred in the area that is now Mexico, triggered...
