Specimen Data (Morphology)

The species is defined by the type specimen, ATD6-69, a juvenile partial facial cranium; the individual estimated to be between 10 and 11.5 years old. The specimen shows a relatively modern midface that is oriented slightly backwards and inferiorly sloping to produce a canine fossa. This specimen also displays a horizontal zygomaxillary border and a sharp lower nasal margin. There is evidence that suggests sinus expansion during adolescence that would fill in the maxillary hollow space, this would make the Pleistocene samples not resemble modern humans once they reached adulthood. Homo antecessor has a prominent double-arched supraorbital torus and a protruding occipital bun, both are distinctly primitive features. Postcranially, the axial skeleton closely resembles anatomically modern Homo sapiens while the slender clavicle is more aligned with Homo neanderthalensis
