Additional information Gordion, Ankara, Turkey (floating series) - turk029 Peter I. Kuniholm, Maryanne Newton, Bryant Bannister, Jeffrey S. Dean. Sections stored at: Malcolm and Carolyn Wiener Laboratory for Aegean and Near Eastern Dendrochronology B48 Goldwin Smith Hall Cornell University Ithaca, NY 14853 Included in this collection are Tree-ring measurements for GOR-2ABCD, a section of Juniperus foetidissima from Tumulus MM with 431 rings, Tree-ring measurements for GOR-3E, a section of Juniperus excelsa from Tumulus MM with 759 rings, and Tree-ring measurements for GOR-161AB, a section of Juniperus excelsa from the Kizlarkaya Tumulus with 863 rings, and the 1028-year-long Gordion juniper chronology from these two tumuli so that readers may inspect for themselves the quality of the fits. These are the three overlapping specimens for which wiggle-matching determinations were reported in Science (Dec. 2001). See articles by Kromer et al., and by Manning et al. A note about MMTRD (or Midas Mound Relative Dating): Several pieces from Tumulus MM end in Relative Year 1764 with the bark of the felling year present. On GOR-3E which ends in RD 1762 the last two rings were countable but not measurable. We have resisted converting these relative dates for some 188 timbers at Gordion to proper BC dates because the link to the living trees of the Anatolian Plateau has not yet been established. When that happens, we will do it at once. Our best estimate for MMTRD 1764 is 740 BC +4/-7 years, although as noted in the Antiquity articles we think the error margin may be lower.
