Qingmenodus is a genus of prehistoric lobe-finned fish. Fossils of Qingmenodus were found in China and date back to the Early Devonian period. Qingmenodus reveals the first well-ossified otoccipital braincase in onychodonts. Palaeontologists believe that Qingmenodus was one of the oldest onychodont fish.[1]
