Cosmogenic aluminum-26 and beryllium-10 burial dates of low-lying fossiliferous breccia in the caves at Sterkfontein, South Africa, show that associated hominid fossils accumulated in the Lower Pliocene. These dates indicate that the skeleton StW 573 and newly discovered specimens from Jacovec Cavern have much the same age: approximately 4 million years. These specimens are thus of an age similar to Australopithecus anamensis from East Africa.
对南非斯泰克方丹洞穴中低洼含化石角砾岩的宇宙成因铝 - 26和铍 - 10埋藏年代测定表明，相关的原始人类化石是在下新世堆积形成的。这些年代测定结果显示，骨架StW 573以及在雅科维奇洞穴新发现的标本具有大致相同的年代：约400万年。因此，这些标本的年代与来自东非的南方古猿阿法种相近。
