A bela história do impacto do asteróide [Chicxulub impact theory] vai com com certeza sobreviver alegremente às provas que a contradizem. Por muitos, muitos anos.

At one site at El Penon, the researchers found 52 species present in sediments below the impact spherule layer, and counted all 52 still present in layers above the spherules.The scientists also found evidence that the Chicxulub impact didn't have the dramatic impact on species diversity that has been suggested.
