Scientists Challenge the 'Chicxulub Crater' Theory The Yucatan Times
go to original June 28, 2014

Until recently, most scientists agreed that the dinosaurs were wiped off the face of the Earth by a 10km-wide meteorite that smashed into the Yucatan Peninsula in Mexico, causing worldwide forest fires, tsunamis several kilometres high, and an ‘impact winter’ – in which dust blocked out the sun for months or years. It was thought that the dinosaurs were blasted, roasted and frozen to death, in that order.

But now a small but vociferous group of scientists believes there is increasing evidence that this ‘impact’ theory could be wrong. That suggestion has generated one of the bitterest scientific rows of recent times.

The impact theory was beautifully simple and appealing. Much of its evidence was drawn from a thin layer of rock known as the ‘KT boundary’. This layer is 65 million years old (which is around the time when the dinosaurs disappeared) and is found around the world exposed in cliffs and mines.

... But a group of scientists led by Prof Gerta Keller of Princeton and Prof Wolfgang Stinnesbeck of the University of Karlsruhe begged to differ. They uncovered a series of geological clues which suggests the truth may be far more complicated. In short, that the crater in the Yucatan is too old to have killed off the dinosaurs.
