We present a mandible recovered in 2003 from the Aurora Stratum of the TD6 level of the Gran Dolina site (Sierra de Atapuerca, northern Spain). The specimen, catalogued as ATD6-96, adds to the hominin sample recovered from this site in 1994-1996, and assigned to Homo antecessor. ATD6-96 is the left half of a gracile mandible belonging to a probably female adult individual with premolars and molars in place. This mandible shows a primitive structural pattern shared with all African and Asian Homo species. However, it is small and exhibits a remarkable gracility, a trait shared only with the Early and Middle Pleistocene Chinese hominins. Furthermore, none of the mandibular features considered apomorphic in the European Middle and Early Upper Pleistocene hominin lineage are present in ATD6-96. This evidence reinforces the taxonomic identity of H. antecessor and is consistent with the hypothesis of a close relationship between this species and Homo sapiens.
我们展示了一块于2003年从西班牙北部阿塔普埃尔卡山脉格兰多利纳遗址TD6层的奥罗拉地层中出土的下颌骨。该标本编号为ATD6 - 96，补充了1994 - 1996年从该遗址出土的归入先驱人的古人类样本。ATD6 - 96是一块纤细下颌骨的左半部分，属于一名可能为成年女性的个体，其前磨牙和磨牙完好。这块下颌骨呈现出与所有非洲和亚洲人属物种共有的原始结构模式。然而，它体积小且极为纤细，这一特征仅与早更新世和中更新世的中国古人类相同。此外，欧洲中更新世和早更新世晚期古人类谱系中被视为鉴别特征的下颌特征在ATD6 - 96中均未出现。这一证据强化了先驱人的分类身份，并且与该物种和智人之间存在密切关系的假设相一致。
