skalletyp

Skalletyp is a Swedish term used in anthropology and archaeology to refer to the classification of skull shapes based on cranial dimensions. The central concept is the cephalic index, calculated as the maximum cranial breadth divided by the maximum cranial length, multiplied by 100. Based on this index, skulls have traditionally been grouped into dolichocephalic (long-headed), mesocephalic (average), and brachycephalic (short-headed) types. Thresholds for these categories vary by study, but commonly dolichocephalic skulls have a cephalic index below about 75, mesocephalic skulls around 75–80, and brachycephalic skulls above about 80.

Historically, skalletyper were used in physical anthropology and archaeology to describe and compare populations. In the late 19th and early 20th centuries, such classifications were linked to broader racial typologies and often accompanied by speculative claims about heredity, climate, and culture. Modern science regards fixed “types” of skulls as unreliable indicators of ethnicity, race, or behavior, and the practice is considered methodologically and ethically problematic when used to draw broad conclusions about groups.

Contemporary use of the concept is limited. Skalletyp is usually referenced descriptively in osteology or forensic anthropology to document cranial morphology, or in historical discussions of the development of anthropological methods. Current perspectives emphasize continuous variation in skull shape, significant overlap among populations, and the influence of age, sex, and environment, rather than rigid typologies.
