Abstract: The bony fishes gave rise to two living subgroups, the ray-finned fishes, and the lobe-fins and tetrapods (or land vertebrates, including ourselves). An analysis of the evolutionary position of a 400-million-year-old fossil both adds to the current picture of bony-fish origins and complicates it — the fossil has such a mix of characteristics that large parts of the vertebrate family tree come into question.
