Submission + - Clearing an asteroid's sullied name ( 1

mlimber writes: A 'Newsweek' science blog discusses the acquittal of the asteroid that is accused of killing the dinosaurs: 'This idea, first proposed in 1980 and widely adopted a decade later, has entered the public consciousness like few others in science. Too bad it doesn't have nearly the credibility among geoscientists as it does in local sandboxes and Hollywood: evidence keeps emerging that the asteroid was framed.

'Instead, a series of titanic volcanic eruptions in India may have wiped out T. rex and his friends (and prey). That idea has been around for a while, but today paleontologist Gerta Keller, who has long been dubious about the asteroid theory, will unveil the strongest evidence yet that scientists convicted the wrong perp. In a study presented at the annual meeting of the Geological Society of America in Denver, she will announce that the volcanic eruptions that created the enormous Deccan Traps lava beds in India peaked at just the right time to explain the dinos' demise.'

  • 1 - an asteroid created the Shiva Crater at roughly the same time the K-T asteroid hit at Chicxulub, hitting the area, causing more volcanic activity. Maybe around the same geological time, maybe fragments of the same asteroid hitting in more than one location.

    2 - the K-T asteroid hit send shockwaves out in concentric waves. The problem with doing that on a sphere is the waves re-converge at the opposite side of the sphere. India was still tracking northwards en route to its collision with Asia, and would h
