In 1986 and 1987, a hominid left ilium fragment consisting of a spina iliaca anterior superior and crista iliaca was discovered during excavations at Sterkfontein, South Africa. Although the specimen is small it gives valuable hints for muscle insertions and origins at the pelvis of Australopithecus africanus. It indicates that the anatomy of the abdominal muscles and of the mm. glutei medius et minimus of A. africanus was quite different from that of the great apes and more similar to that of modern humans. This has major implications for the interpretation of the bipedalism and locomotor efficiency of the early South African hominids.
1986年和1987年，在南非斯特克方丹的发掘过程中，发现了一块由髂前上棘和髂嵴组成的原始人类左髂骨碎片。尽管该标本较小，但它为非洲南方古猿骨盆处肌肉的附着和起源提供了有价值的线索。这表明非洲南方古猿的腹部肌肉以及臀中肌和臀小肌的解剖结构与大猩猩有很大不同，而更类似于现代人类。这对于解释早期南非原始人类的双足行走和运动效率具有重要意义。
