Broken Hill 1, or Kabwe 1, is noted is noted for its massive facial features, including a thick supraorbital tori, relatively large canines, and a receding frontal bone¹. Despite its robust face, the zygomatic arch preserved on the right side is relatively gracile and post orbital constriction is minimal². One of the most notable features on this fossil is the evidence for extreme tooth decay in 10 of the 16 maxillary teeth, and abscesses in the jaw^1,3. Molars appear modern, in that the upper third molar is smaller than the first and second molars².
