Three bones found in Japan decades ago have revealed a giant salamander unlike any known species

Three fossilised bones dug up in Japan nearly thirty years ago have finally revealed their true identity, and it turns out to be something scientists had never formally recognised before. The remains belong to a giant salamander that lived around 3.5 million years ago in the lakes and wetlands of what is now northern Kyushu, and researchers have now given it a brand new name, Limnospondylus ajimuensis. The animal may have grown to about 1.1 metres in length, making it roughly comparable in size to some of the largest amphibians alive today, and estimates suggest it could have reached that length at around eighteen years old.How old bones from Oita Prefecture led to a new discoveryThe three fossilised vertebrae were originally found between 1995 and 1997 in the Ajimu region of Oita Prefecture, inside a layer of ancient lake sediment known as the Tsubusugawa Formation.
