New species whose remains were found in the Chinese province of Liaoning, was named Beiyanerpeton jianpingensis. Age findings was determined by analysis of the ratio of isotopes of uranium and lead in ambient ground remains it turned out to be 157 million years old. Age previous record holders, according to scientists, was 112-114 million years.


According to the researchers, the new species belongs to the suborder Salamandroidea.
