ACKNOWLEDGMENTS
We are very thankful to the anonymous donor of this valuable specimen. We are also grateful to T. Ozawa (CYU), T. Kimura (GMNH), O. Lambert (IRSNB), M. Fornasiero (MGPU), U. Göhlich (NMW), and C. de Muizon and C. Argot (MNHN) who kindly provided one of us (H.I.) access to the collections of both fossil and extant long-snouted toothed whales under their care. The comments of R. E. Fordyce considerably enhanced an earlier version of the manuscript. M. Murakami (WU), L. G. Barnes (LACM), R. E. Fordyce (OU), and O. Lambert (IRSNB) were of great help in providing photographs of specimens for critical comparisons with the specimen from South Korea. We also wish to thank Mizuki Murakami (WU), R. E. Fordyce (OU), M. Fornasiero (MGPU), and O. Lambert (IRSNB) for providing literature on platanistoids and other fossil long-snouted odontocetes. This research is supported by the Basic Research Project (No. 11-3114) of KIGAM funded by the Ministry of Knowledge Economy of Korea to the first author.
