The transition to maize agriculture frames important cultural shifts in the Eastern Woodlands. However, the tempo and mode of this transition are unclear, particularly when analytical techniques are not standard across the region. In this article, we present evidence of directly dated maize macrobotanical fragments from the Turpin site in southwest Ohio that date between cal AD 552–649 and 684–994. These dates add to current dialogues on the spread of maize in the American Midcontinent and help further situate the Middle Ohio Valley as a cultural crossroads through which people and ideas flowed. We echo suggestions that, to refine our understanding of the introduction of maize into the region, we must develop pan-regional analytical standards and create multiple working hypotheses at a variety of scales.

向玉米农业的转变构成了东部林地重要的文化转变。然而，这种转变的节奏和模式尚不清楚，特别是当分析技术在整个地区尚未标准化时。在本文中，我们提供了来自俄亥俄州西南部特平遗址的直接定年玉米大型植物碎片的证据，其年代可追溯到公元 552-649 年和 684-994 年之间。这些日期丰富了当前关于美国中部大陆玉米传播的对话，并有助于进一步将俄亥俄河谷中部定位为人员和思想流动的文化十字路口。我们同意这样的建议：为了加深我们对玉米引入该地区的理解，我们必须制定泛区域分析标准并在不同尺度上提出多种工作假设。
