- The Caribbean and Mesoamerica Biogeochemical Isotope Overview (CAMBIO)Publication . Ebert, Claire E.; Hixon, Sean W.; Buckley, Gina M.; George, Richard J.; Pacheco-Fores, Sofía I.; Palomo, Juan Manuel; Sharpe, Ashley E.; Solís-Torres, Óscar R.; Davis, J. Britt; Fernandes, Ricardo; Kennett, Douglas J.The Caribbean & Mesoamerica Biogeochemical Isotope Overview (CAMBIO) is an archaeological data community designed to integrate published biogeochemical data from the Caribbean, Mesoamerica, and southern Central America to address questions about dynamic interactions among humans, animals, and the environment in the region over the past 10,000 years. Here we present the CAMBIO human dataset, which consists of more than 16,000 isotopic measurements from human skeletal tissue samples (delta 13C, delta 15N, delta 34S, delta 18O, 87Sr/86Sr, 206/204Pb, 207/204Pb, 208/204Pb, 207/206Pb) from 290 archaeological sites dating between 7000 BC to modern times. The open-access dataset also includes detailed chronological, contextual, and laboratory/sample preparation information for each measurement. The collated data are deposited on the open-access CAMBIO data community via the Pandora Initiative data platform (https://pandoradata.earth/organization/cambio).
- Earliest evidence for intentional cremation of human remains in AfricaPublication . Cerezo-Román, Jessica I.; Sawchuk, Elizabeth; Schilt, Flora Cecilia; Bertacchi, Alex; Buckley, Gina; Chibisa, Edwin; Fahey, B. Patrick; Falchenberg, Sofia Gunilla Hedman; Kaliba, Potiphar; Kennett, Douglas J.; Mercader, Julio; Pargeter, Justin; Stock, Jay; Szymanski, Ryan; Thompson, Jessica C.Human cremation on an open pyre demands intensive labor, communal resources, and sensory exposures. We report the earliest evidence for intentional cremation in Africa, the oldest in situ adult pyre in the world, and one of only a few associated with hunter-gatherers. A large cremation feature at Hora 1 in Malawi dates to similar to 9500 years ago and contains the remains of a small, gracile adult with evidence for perimortem defleshing and postcremation manipulation. Subsequent revisiting of the site to build fires in the same place provided additional pyrotechnological spectacles. High-resolution, multiproxy reconstruction of the ritual associated with cremation and its subsequent deposition demonstrates complex mortuary practices among ancient African foraging groups with substantial social investment and use of natural landscape features as persistent mortuary monuments.
