Sparacello, F. Bertoldi, O. Fonzo, C. Malone, E. Marini, F. Martinet, J. Moggi-Cecchi, E. Pacciani, L. Raiteri, J. T. Stock

    Published 2023-12-01
    “…We investigate the interplay between skeletal growth, diet, physical activity and population size across 30,000 years in the central Mediterranean through a ‘big data’ cross-analysis of osteological data related to stature (n = 361), body mass (n = 334) and long bone biomechanics (n = 481), carbon (δ 13C) and nitrogen (δ 15N) stable isotopes (n = 1986 human, n = 475 animal) and radiocarbon dates (n = 5263). We present the observed trends on a continuous timescale in order to avoid grouping our data into assigned ‘time periods’, thus achieving greater resolution and chronological control over our analysis. …”

    Subsistence of early anatomically modern humans in Europe as evidenced in the Protoaurignacian occupations of Fumane Cave, Italy by Ana B. Marín-Arroyo, Gabriele Terlato, Marco Vidal-Cordasco, Marco Peresani

    Published 2023-03-01
    “…Here, we present the subsistence regimen adopted by the Protoaurignacian groups in two different levels in Fumane Cave based on archaeozoological data. New radiocarbon dates confirm an overlap between Uluzzian and Protoaurignacian occupations, around 42 and 41,000 cal BP, and reveal that modern humans occupied the cave from GI10 to GS9, the last level coinciding with the Heinrich Event 4. …”

    Accumulation of radiocarbon in ancient landscapes: A small but significant input of unknown origin by Adrian Broz, Jerod Aguilar, Xiaomei Xu, Lucas C. R. Silva

    Published 2023-05-01
    “…Total organic C, measured in three individual profiles spanning depth transects from the outcrop surface to a 1-m depth, ranged from 0.01 to 0.2 wt% with no clear C-concentration or age-depth profile. Ten radiocarbon dates from the same profiles reveal radiocarbon ages of ~ 11,000–30,000 years BP that unexpectedly indicate additions of potentially modern organic C. …”

    Dating old hollow trees by applying a multistep tree-ring and radiocarbon procedure to trunk and exposed roots by Gianluca Piovesan, Franco Biondi, Michele Baliva, Lucio Calcagnile, Gianluca Quarta, Alfredo Di Filippo

    Published 2018-01-01
    “…The method can be illustrated by the following steps: • crossdated tree-ring series from trunk cores reveal a multi-century tree age, and the hollow section is large enough to contain several more years (decades to centuries) • exposed roots can be cored for acquiring wood samples older than the stem cores and for construction of a floating root average tree-ring series • if synchronization between stem and exposed roots is unclear, proceed to date the root wood samples by radiocarbon wiggle matching; match root and stem tree-ring series within the radiocarbon-dated period to more accurately date the tree.This new multistep dating method allowed for refining the age estimation of the oldest Pinus heldreichii tree in Pollino National Park by 166 years, to 789 CE. …”
