An international team has discovered the first known stem amphibian to have lived entirely in the sea. Named *Gerrothorax maritimus*, it is known from two nearly complete skeletons found in China’s Guizhou Province and dating to about 237 million years ago. Each skeleton was at least 737 millimeters long and revealed a flattened body, heavy bony armor, and well-developed gills—features that likely helped the animal live on the seafloor, breathe underwater, and reduce water loss through its skin.
