アウストラロピテクス・アファレンシス
Greenstick fractures are found in the fossil remains of Lucy, the most famous specimen of "Australopithecus afarensis", discovered in Ethiopia in 1974. Analysis of bone fracture patterns, which include a large number of greenstick fractures in the forearms, lower limbs, pelvis, thorax and skull, suggest that Lucy died from a vertical fall and impact with the ground.
