U-Pb ages of single shocked zircons linking distal K/T ejecta to the Chicxulub crater

The impact breccia from Chicxulub contains zircons that are identical in age to Colorado zircons and to some from the Beloc section of Haiti. Study results point to Chicxulub as the only significant Cretaceous/Tertiary impact crater.
