Scientists in Mexico have uncovered a groundbreaking fossil discovery: Ambystoma quetzalcoatli, the first known fossil salamander in the country and the oldest record of its genus. Found in ancient lakebeds of Hidalgo, the fossils reveal a distinct, prehistoric axolotl with unique skull and skeletal traits—including 17 trunk vertebrae—differing from today’s 16 or fewer. Using CT scans and modern comparisons with 13 living species, researchers confirmed it’s a new species. This find reshapes our understanding of axolotl evolution, pushing their presence in Mexico back millions of years to the Pliocene and showing neoteny was already in place.
