New isotopic ages and a fresh understanding of stratigraphic relations among siliciclastic strata in the Pensacola Mountains along the northern margin of the East Antarctic craton result in removal of some constraints for the Proterozoic break-up of Rodinia and necessitate revision of the subsequent...
