Metric data of GN-999 (black star) in comparison to metric data of seven canid groups (see Table S2): Modern dogs (n = 2, reference collection Uni Tübingen); Modern wolves (n = 4, reference collection Uni Tübingen and Bonn); Pleistocene wolves (n = 7, Brillenhöhle, Kesslerloch, Geißenklösterle. The four groups ‘Archaic dogs’ (n = 27), ‘Palaeolithic dogs’ (n = 31), ‘Northern wolves’ (n = 35) and ‘Pleistocene wolves’ (n = 36) are defined by Germonpré and colleagues³⁵ and defined by mean value and standard deviation.
