In 1995, a 1.8 million year old hominid maxilla with complete dentition (OH 65) was excavated from Bed I in the western part of Olduvai Gorge. The molar crowns are small relative to the long flaring roots, and the root of the canine is very long and straight. The broad maxilla with wide U-shaped palate and the form of the tooth roots closely match those of KNM-ER 1470 which, in its parietal size and morphology, matches the type specimen of Homo habilis, OH 7. Thus, OH 65 and KNM-ER 1470 group with OH 7 as representatives of H. habilis while some other Olduvai specimens, such as OH 13 and OH 24, have more in common in terms of morphology and brain size with Australopithecus africanus. Between 1995 and 2007, the OLAPP team has recovered teeth of eight other hominid individuals from various parts of Olduvai Gorge. These have been identified as belonging to H. habilis, Paranthropus boisei, and Australopithecus cf. africanus.
1995 年，在奥杜威峡谷西部的 I 层出土了一块 180 万年前带有完整牙列的人科上颌骨（OH 65）。臼齿的牙冠相对较长的膨大部分较小，而犬齿的根部非常长且直。宽阔的上颌骨带有宽阔的 U 形腭和牙根形态与 KNM-ER 1470 非常吻合，后者在顶骨尺寸和形态上与能人 OH 7 的模式标本相匹配。因此，OH 65 和 KNM-ER 1470 与 OH 7 一起代表能人，而奥杜威的其他一些标本，如 OH 13 和 OH 24，在形态和脑容量方面与南方古猿非洲种更为相似。1995 年至 2007 年期间，OLAPP 团队从古人类的不同部位回收了其他 8 颗牙齿。这些牙齿被鉴定为能人、粗壮南猿和南方古猿 cf. 非洲种。
