Vertebra of a Bowhead whale (Balaena mysticetus) in Late Wisconsinan deglacial marine sediments, Trout River, Newfoundland, and local late-glacial sea-level change
This note reports the geological contexts and radiocarbon and calibrated ages of whalebone and bivalve recovered from emerged deglacial marine sediments at Trout River, Newfoundland (49°28.6’ N, 58°07’ W). The rate of sea-level fall is calculated for the first deglacial millennium, and discrepancies...

| Summary: | This note reports the geological contexts and radiocarbon and calibrated ages of whalebone and bivalve recovered from emerged deglacial marine sediments at Trout River, Newfoundland (49°28.6’ N, 58°07’ W). The rate of sea-level fall is calculated for the first deglacial millennium, and discrepancies are noted between calibrated ages of bone and shell. Cette note fait état du contexte géologique et des âges radiocarbone et calibrés d’une vertèbre de baleine et d’un coquillage issus de dépôts marins tardiglaciaires à Trout River, Terre-Neuve (49°28.6’ N, 58°07’ W). Le taux de diminution du niveau de la mer est calculé pour le premier millénaire, et la divergence des âges entre l’os et le coquillage est discutée. |
