Both specimens show a remarkable change in δ^<18>O from light values in the first six or seven septa to heavier ones in the succeeding septa, and this is probably due to the hatching. Water temperatures estimated from δ^<18>O values of the septa do not coincide with the actual temperatures in the Nautilus habitat. This fact suggests a possibility of the oxygen isotopic disequilibrium among the septa, cameral fluid and surrounding seawater.}, pages = {26--29}, title = {Oxygen Isotope Analysis of the Shells of Nautilus pompilius from Tañon Strait, the Philippines}, volume = {1}, year = {} }
