This study was undertaken to evaluate the accuracy of amino acid chronology using a first‐order kinetic model and was carried out using a fossil planktonic foraminifera, Pulleniatina obliquiloculata (P. obliquiloculata), in the sediment from the western equatorial Pacific Ocean. The extent of racemi...
