【 摘 要 】

Underwater deposits, especially those in phreatic caves, often contain exquisitely preserved fossils, and many represent Quaternary Konservat-Lagerstätten. Nevertheless, they are unrecognised as such by most practicing palaeontologists. This review highlights the unique contributions to palaeontology made by underwater deposits as well as the technical and practical challenges facing underwater palaeontologists. Recovery of fossils from such deposits requires specialist training, equipment, and procedures unique to these environments. Taphonomic studies of underwater assemblages are rare and hampered by difficulties in fossil recovery. Neotaphonomic experiments and observations of modern accumulations in underwater settings should be a priority for future research. Regions where such techniques might provide important new insights into Quaternary faunas and environments, not accessible through traditional palaeontological approaches, include low-lying flooded continental shelves and soil-poor karstic landscapes. Underwater palaeontology represents a largely unexplored yet significant source of fossils, further study of which will expand and enrich traditional approaches in the study of ancient organisms.
