Relating to or connecting the forehead and the ear; used in anatomy and anthropology.
From Latin 'frons' (forehead) + 'auricular' (relating to ears, from Latin 'auricula'). This is a medical/anatomical compound adjective.
Anatomists create compound adjectives like this to precisely describe relationships between body parts, and knowing which measurements connect (frontoauricular, frontomaxillary) is crucial for anthropology because skull proportions reveal evolutionary relationships between species.
