Ten vertebral elements from the AL-288 partial hominid skeleton and 11 elements from the AL-333 collection are described. The AL-288 column presents a marked kyphosis at the level of thoracic vertebrae 6 through 10, with pronounced new bone formation on the ventral surfaces of these vertebrae. These features, associated with narrowed disc space and minor osteophytosis, resemble Scheuermann disease in the human. Even though this diagnosis is consistent with a basically human, bipedal locomotor repertoire, the presence of Scheuermann disease suggests that lifting, climbing, or acrobatic activities may have been important in early hominids.
描述了来自AL - 288部分原始人类骨骼的10个椎骨元件以及来自AL - 333集合的11个元件。AL - 288脊柱在第6至10胸椎水平呈现明显的脊柱后凸，这些椎体腹侧有明显的新骨形成。这些特征，连同椎间盘间隙变窄和轻度骨赘形成，类似于人类的休门氏病。尽管这种诊断与基本的人类双足运动模式一致，但休门氏病的存在表明，在早期原始人类中，举物、攀爬或杂技活动可能很重要。
