Researchers unearth fossil evidence of 1st fully marine amphibian

Scientists have uncovered fossil evidence of the first fully marine amphibian, with the research published in Nature Ecology & Evolution. They named the armoured, giant salamander-sized, bottom-dwelling ocean creature Gerrothorax maritimus after analysing two nearly complete 237-million-year-old skeletons. The fossils were discovered in an area of China's Guizhou that was once covered by ocean.
