Researchers have identified a new fossil species of axolotl in Mexico, the first fossil salamander formally described in the country.
Researchers at the Zaragoza School of Advanced Studies at the National Autonomous University of Mexico identified the species in the state of Hidalgo.
The new species has been named Ambystoma quetzalcoatli. It provides evidence that axolotls have inhabited Mexico for millions of years.
This marks the first formal identification of a fossil salamander from the country.
