title = "Earliest isotopic evidence in the Maya region for animal management and long-distance trade at the site of Ceibal, Guatemala",
abstract = "This study uses a multiisotope (carbon, nitrogen, oxygen, and strontium) approach to examine early animal management in the Maya region. An analysis of faunal specimens across almost 2,000 years (1000 BC to AD 950) at the site of Ceibal, Guatemala, reveals the earliest evidence for live-traded dogs and possible captive-reared taxa in the Americas. These animals may have been procured for ceremonial functions based on their location in the monumental site core, suggesting that animal management and trade began in the Maya area to promote special events, activities that were critical in the development of state society. Isotopic evidence for animal captivity at Ceibal reveals that animal management played a greater role in Maya communities than previously believed.",

note = "Funding Information: We thank the archaeologists and excavators of the Ceibal-Petexbatun Archaeological Project who recovered the faunal material used in this study. We also thank Erin Thornton and Camilla Speller for the turkey ancient DNA analysis, and Nicole Cannarozzi and Arianne Boileau for assisting with the radiocarbon sampling of the dog and feline mandibles. We thank Jason Curtis for analyzing the light isotope samples on the mass spectrometers at the Light Stable Isotope Mass Spectrometer Laboratory, Department of Geological Sciences, University of Florida. We also thank the two anonymous reviewers for their most valuable and constructive suggestions. Funding for the export and isotope analysis of the remains was made possible by the National Science Foundation (Doctoral Dissertation Improvement Grant 1433043 to K.F.E. and A.E.S.), and the Sigma Xi Scientific Research Society, the University of Florida Latin American Studies Program Tinker Grant, and the University of Florida Department of Anthropology Charles Fairbanks Award (to A.E.S.). Radiocarbon dating was conducted with funding from the Alphawood Foundation (T.I.).
