A.L. 288-1: a Lovejoy et al.29, b Tague and Lovejoy18, c Häusler and Schmid19, d Brassey et al.20; Sts 14: e Häusler and Schmid19, f Berge and Goularas17; g modern human female pelvis and fetal head (in inset); MH2: h Kibii et al.21, i Laudicina et al.22. All pelves are seen in a view perpendicular to the pelvic inlet. Scale bar 5 cm.
