Ancient Giant Salamander Fossil Discovered in Japan Sheds Light on Evolution
Researchers have uncovered fossils of a giant salamander in Japan, dating back 3.5 million years. The fossils, found in the Ajimu area of Oita Prefecture, belong to a previously unknown genus and species, Limnospondylus ajimuensis. The discovery provides insights into the evolutionary history of giant salamanders and their adaptation to changing environments. The region once supported a warm, subtropical ecosystem, which has since cooled, leading to the disappearance of the species.
