American Caucasoid

Being able to see the oval window through the external auditory meatus on a dry cranial specimin has recently been discovered to be of some importance in differentiating between Caucasoid and American Indian, or Mongoloid skeletal remains (Birkby, Walter H., Napoli, Michelle L., Maxwell Papers #4, 1992). The window is seen because the opening of the meatus is longer and wider in Caucasoids. .
