The oldest fossil salamanders

Six specimens of salamanders have recently been discovered at the bottom of a dry lake in China and identified a group of paleontologists from the University of Beijing and University of Chicago as the oldest Salamandroidea specimens of the species ever found on Earth. As noted by the scientists in their paper published in Proceedings of the National Academy of Sciences . the age of the fossil is equal to approximately 157 million years old.

The samples, which was named by researchers Beiyanerpeton jianpingensis, were discovered in Liaoning province, in the area Taityanskogo layer (Tiaojishan Formation). A group of researchers reported that animals probably looked like the look of the Salamander today: a long body and tail, short legs. The adults are nearly four inches (10 centimeters) in length. However, tapered tail and gills on the body of these animals a very special kind, and the discovery of their remains on the bottom of an ancient lake, indicates that the ancestors of modern salamanders most of his life spent under water. The team also noted that salamanders usually have a very unique appearance, which greatly facilitates their identification.

After a detailed examination of the findings of the international research group suggested that salamanders, apparently, began to differ Continue reading
