Having a long, narrow cranium or braincase, describing skull shape from the perspective of the entire cranial vault.
From Greek 'dolichOS' (long) and 'kranion' (skull), a technical anatomical term distinguishing overall skull elongation from just the head's shape.
Dolichocranial measurements helped paleontologists understand how our brains evolved, since cranial volume correlates with brain size—though they later realized skull shape and intelligence have virtually no relationship.
