چکیده
t f p A single vertebra from an Early Formative period archaeological ite in coastal Chiapas, México, is identified as belonging to the mphibian Dermophis mexicanus (Duméril and Bibron) 1841 Amphibia: Gymnophiona: Caeciliidae). The vertebra was recovered rom deposits dated to approximately 1200–1350 B.C. The specimen epresents the first Quaternary fossil record for gymnophiones. Its resence suggests the possible role of the species as a bioturbator. Its ecovery is further evidence of the utility of fine-grained archaeologcal recovery techniques. © 1999 University of Washington.
