Description :
Thirty-nine species of scleractinian corals, associated with thin intertidal sediments, have been recovered from under a high dune on the western (mainland) side of North Stradbroke Island, eastern Australia. Three species yielded a mean 230Th/234U age of 105,000 yr BP. The corals provide evidence of a sea stand near present sea level during isotope Stage 5c, which is considerably higher than previously suggested for this period. Their good condition implies that the overlying parabolic dune is of comparable age and formed during that high stand of sea level. Also, the isotope age provides a maximum period for the development of giant podzols in the podzol chronosequences on coastal dunes in southern Queensland.
