Usage
The term is a specialized adjective used almost exclusively in scientific contexts, particularly physical anthropology, to classify human skull shapes based on cranial index measurements. * The anthropologist noted the dolichocranic features of the ancient skull. * Populations in certain regions show a higher frequency of dolichocranic individuals.
Advanced Usage
