The living and the dead: How do taphonomic processes modify relative abundance and skeletal completeness of freshwater fish?

摘要: Abstract This study is designed to determine the extent which taphonomic processes alter taxonomic composition of fish remains in lacustrine sediments. We wish explore information loss a bone assemblage relative original, living community. examined assemblages from sediments along southern shore Lake Kinneret (Sea Galilee) and compared them modern communities. For this purpose we randomly selected 24 squares, each 0.5 m2 size, excavated depth 30–50 cm. Three lithofacies were recovered, spanning past 1500 years (unccorected for reservoir age). The include 5037 bones 758 scales, 1566 identified group. list species was with indigenous known live general similar sandy habitat particular. proportion skeletal elements found complete fish. Our indicates that differences exist between three diversity composition, element richness, completeness, abundance. In addition, exhibit clumped distribution pattern, regardless depositional depth. From paleoecological perspective, our findings demonstrate retrieved do not represent as recent
