Seventeen hominoid fossils recovered from Pliocene strata at Aramis, Middle Awash, Ethiopia make up a series comprising dental, cranial and postcranial specimens dated to around 4.4 million years ago. When compared with Australopithecus afarensis and with modern and fossil apes the Aramis fossil hominids are recognized as a new species of Australopithecus--A. ramidus sp. nov. The antiquity and primitive morphology of A. ramidus suggests that it represents a long-sought potential root species for the Hominidae.
从埃塞俄比亚中阿瓦什地区阿法尔的上新世地层中发现的17件类人猿化石,构成了一个可追溯至约440万年前的系列,包括牙齿、颅骨和颅后标本。与阿法南方古猿、现代猿类及化石猿类相比,阿法尔化石人科动物被认定为南方古猿的一个新物种——南方古猿始祖种。南方古猿始祖种的古老性和原始形态表明,它代表了长期以来人们一直在寻找的人科潜在根源物种。
