title: A gradient of size and shape for the Atapuerca sample and Middle Pleistocene hominid variability.
abstract: The Atapuerca sample reveals that differential development of morphology of distinct areas of the mandible gives rise to a spectrum of morphology which virtually encompasses the entire range of variability detected in European Middle Pleistocene samples. Two new mandibles collected at Atapuerca SH site (Spain) give new insight into this matter. Specimen AT-950 demonstrates that there is a continuum between the peculiar morphology of Mauer and other Middle Pleistocene specimens. Specimen AT-888 increases the size range, and also sheds light on the significance of traits such as the retromolar space and the position of the mental foramen.
