Salamander Species Deemed World's Oldest, Beiyanerpeton Jianpingensis, Lived 157 Million Years Ago

A newly discovered 157-million-year-old salamander is the oldest of its kind and would've swum with the aquatic beasts of the Jurassic. The discovery supports the idea that this order diverged from other salamanders earlier than thought, the researchers said. Six specimens of this new species, now called Beiyanerpeton jianpingensis, were discovered in the Tiaojishan Formation, in Liaoning Province, China.
