 In addition, other studies using radiocarbon dating to study sea level and the age of sediment and beachrock within the Bahamas have not reported any significant problems with contamination by younger radiocarbon.In their detailed research, Davaud and Strasser accepted the radiocarbon dates obtained from the beachrock composing the Bimini Road from the radiocarbon laboratory at the University of Miami as valid indicators of its age.Gifford and Ball attempted to establish a minimum age using uranium-thorium dating for the Bimini Road by dating a whole-rock sample of the marine limestone (biopelsparite) that underlies the beachrock that composes the Bimini Road.
