Nasal Concha

One of six curled bones (plural: conchae) that extend medially from the lateral walls of the nasal cavity; in life they are covered with mucosa that help filter, warm, and humidify the inspired air. Recent research suggests that Neandertals had larger conchae than moderns, perhaps as an adaptation to their cold environment. Aka turbinate bone, especially in skeletal specimens.
