    Abstract
    The timing of the initial dispersal of hominins
    into Eurasia is unclear. Current evidence
    indicates hominins were present at Dmanisi,
    Georgia by 1.8 million years ago (Ma), but other
    ephemeral traces of hominins across Eurasia
    predate Dmanisi. However, no hominin remains
    have been definitively described from Europe
    until ~1.4 Ma. Here we present evidence of hominin
    activity at the site of Grăunceanu, Romania in
    the form of multiple cut-marked bones.
    Biostratigraphic and high-resolution U-Pb age
    estimates suggest Grăunceanu is > 1.95 Ma, making
    this site one of the best-dated early hominin
    localities in Europe. Environmental
    reconstructions based on isotopic analyzes of
    horse dentition suggest Grăunceanu would have
    been relatively temperate and seasonal,
    demonstrating a wide habitat tolerance in even
    the earliest hominins in Eurasia. Our results,
    presented along with multiple other lines of
    evidence, point to a widespread, though perhaps
    intermittent, presence of hominins across
    Eurasia by at least 2.0 Ma.


    "At least 31 taxa (Supplementary Data 1) are
    identified from Grăunceanu, including mammoth,
    multiple species of bovids and cervids,
    giraffids, equids, rhinocerotids, multiple
    carnivore species, rodents (beaver, porcupine),
    ostrich, a large species of terrestrial monkey
    (Paradolichopithecus), and the youngest
    representative of pangolins in Europe.
    Paleoecological analyses suggest Grăunceanu
    was a forest-steppe environment along the
    paleo-Olteţ river."

    "We purposefully avoid discussion of the
    hominin species (or multiple species) that may
    have been the first to disperse into Eurasia.
    This is a period when multiple hominin species
    coexisted at sites in eastern and southern
    Africa. The taxonomic affinity of nearly all
    hominin fossils in Fig. 5 is debated; many are
    identified only to Homo sp. and others are
    identified as Homo erectus/ergaster. Present
    evidence indicates that the earliest H. erectus
    sensu lato was present in both South Africa and
    Ethiopia ca. 2.0 Ma; this therefore broaches the
    possibility that, if hominins were present in
    Eurasia prior to 2.0 Ma, then they may not have
    been H. erectus, and/or that H. erectus is older
    than we currently have data for."
