In Africa, the scarcity of hominin remains found in direct association with stone tools has hindered attempts to link and with particular lithic industries. The infant mandible discovered in level E at Garba IV (Melka Kunture) on the highlands of Ethiopia is critical to this issue due to its direct association with an Oldowan lithic industry. Here, we use synchrotron imaging to examine the internal morphology of the unerupted permanent dentition and confirm its identification as . Additionally, we utilize new palaeomagnetic ages to show that (i) the mandible in level E is ca. 2 million-years-old, and represents one of the earliest fossils, and (ii) that overlying level D, ca. 1.95 million-years-old, contains the earliest known Acheulean assemblage.
在非洲，与石器直接相关的古人类遗骸稀少，这阻碍了人们将[具体古人类物种名称缺失]与特定石器工业联系起来的尝试。在埃塞俄比亚高地加尔巴四世（梅尔卡昆图雷）E层发现的婴儿下颌骨，因其与奥杜威石器工业直接相关，对这个问题至关重要。在这里，我们使用同步加速器成像来检查未萌出恒牙的内部形态，并确认其为[具体古人类物种名称缺失]。此外，我们利用新的古地磁年代测定结果表明：（i）E层的下颌骨约有200万年历史，是最早的[具体古人类物种名称缺失]化石之一；（ii）覆盖其上的D层约有195万年历史，包含已知最早的阿舍利文化组合。
