Bivalve samples collected during the 2001 Exploration of Heceta Bank, including a perfectly intact mussel shell recovered from the Bank's ancient shoreline. The mussel shell has been dated by John Southon at the Lawrence Livermore Laboratory at 13,120 radiocarbon years (translated to 14 to 15 thousand years before present).
