Bony Fish Fossil
The earliest known and well-preserved bony fish has been found in southern China. The fossil of a Guiyu oneiros, described in this week’s Nature journal, sheds light on the evolutionary history of jawed vertebrates.
Previously this was documented almost exclusively from fossil fragments. The fossil represents the oldest near-complete gnathostome (jawed vertebrate) and has been described by Min Zhu and colleagues of the Key Laboratory of Evolutionary Systematics of Vertebrates, Institute of Vertebrate Palaeontology and Palaeoanthropology, Chinese Academy of Sciences.
