Description :
A single vertebra from an Early Formative period archaeological site in coastal Chiapas, Mexico, is identified as belonging to the amphibian Dermophis mexicanus. This specimen represents the first Quaternary fossil record for gymnophiones. Its presence suggests the possible role of the species as a bioturbator. Its recovery is further evidence of the utility of fine-grained archaeological recovery techniques.
