title = "The Naco Clovis Site: Old Excavations and New Dates",
abstract = "Archival research demonstrates that a previously unpublished second season of excavations took place at the Naco Clovis site in 1953, more than doubling the extent of the excavated area and revealing additional bones pertaining to a second mammoth. In 2020 small pieces of charcoal were found in sediment adhering to the distal fragment of a mammoth ulna from the Naco site. The bone was part of a 2011 donation to the Arizona State Museum by David Navarrete, grandson and nephew of the original discoverers of the site. Three AMS radiocarbon dates were obtained from individual wood charcoal fragments, and two more on a sample of multiple charcoal flecks. The first three have a weighted mean of 10,985 ± 56 14C yr BP (13,067–12,767 cal yr BP), fitting within the range of Clovis ages obtained from other Clovis sites; the other two ages are younger.",

note = "Funding Information: First and foremost, the authors are indebted to David Navarrete for donating the mammoth bones collected by Fred and Marc Navarrete to the Arizona State Museum in 2011, and for sharing family photographs in 2019. Both of these were of critical importance in making this project possible. We are also grateful to the current and former Arizona State Museum personnel who facilitated our efforts, including Suzanne Eckert, Alan Ferg, Nancy Odegaard, Todd Pitezel, and Jannelle Weakly. Ferg provided B. Huckell with archival maps and notes, and Weakly shared photographs and documentation from the 1952 and 1953 excavations at Naco. Jeff Saunders, currently overseeing the University of Arizona Laboratory of Paleontology, provided help with mammoth bone identifications. Dating of the Naco Mammoth charcoal samples was supported by the Argonaut Archaeological Research Fund (University of Arizona Foundation; V. T. Holliday, Director), established by the late Joe and Ruth Cramer. Lisa Huckell thanks Adrian Brearley (Department of Earth and Planetary Sciences, University of New Mexico) for use of his high magnification metallurgical microscope. Joseph Birkmann (Department of Anthropology, University of New Mexico) created the maps in and , and skillfully combined the 1952 published map and the 1953 plane table map of the Naco site seen in . Diane Tyink of the Maxwell Museum, University of New Mexico, scanned the image that appears as . Publisher Copyright: {\textcopyright} 2022 Center for the Study of the First Americans.",
