• •Researchers identified Ambystoma quetzalcoatli, the first fossilized salamander species formally documented in Mexico, according to WIRED.
• •The discovery confirms that the lineage of axolotls and related mole salamanders has inhabited the Mexican landscape for millions of years.
• •The precise evolutionary link between this fossil and modern, critically endangered axolotls remains unconfirmed due to gaps in the regional paleontological record.

Paleontologists have identified Ambystoma quetzalcoatli, the first fossil salamander species formally recorded in Mexico. While researchers previously lacked physical proof of ancient axolotl lineage in the region, this discovery extends the known history of the group back millions of years. However, the fossil's discovery highlights a broader scarcity of Mexican vertebrate paleontology, leaving researchers to speculate on how many other species remain undocumented in the area. Whether this find will provide a clear genetic map for modern conservation efforts depends on upcoming genomic comparisons between the fossil and extant populations.
