Tóm tắt

A single vertebra from an Early Formative period archaeological site in coastal Chiapas, México, is identified as belonging to the amphibianDermophis mexicanus(Duméril and Bibron) 1841 (Amphibia: Gymnophiona: Caeciliidae). The vertebra was recovered from deposits dated to approximately 1200–1350 B.C. The 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.
