The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a paper to be published in the Journal of the Geological Society on April 27, 2009.

How big were the first planetesimals? We attempt to answer this question by conducting coagulation simulations in which the planetesimals grow by mutual collisions and form larger bodies and planetary embryos

Ernesto Guido on 29 Apr 09

Gerta Keller (Princeton University) and Thierry Adatte (University of Lausanne) believe the Chicxulub crater in northern Yucatan was formed some 300,000 years before the mass extinction occurred. Moreover, Keller argues in the upcoming Journal of the Geological Society that not a single species went extinct as a result of the impact.
