A cephalic index of 70% corresponds to which head shape?

Explanation:
The cephalic index compares skull width to skull length: CI = (width / length) × 100. A value of 70% means the head is longer than it is wide, giving an elongated shape. That corresponds to dolicocephalic. Brachycephalic, with a broad head, would have a higher CI (roughly over 80–85). Mesocephalic is a mid-range CI, and hyperdolicocephalic would imply an even more extreme elongation with CI well below 70. So a 70% cephalic index best fits the dolicocephalic category.
