Ryan‐Harley (8JE1004) in the Wacissa River of North Florida is one of few sites in the Eastern United States that contains an unfluted lanceolate point component (Suwannee) in a buried context. Extinct and extirpated faunal remains found within the Suwannee artifact layer at Ryan‐Harley have been cited as evidence of a Pleistocene faunal refugium in the Southeastern United States. In 2015, geoarchaeological excavations were undertaken to determine if the Ryan‐Harley Suwannee assemblage is culturally discrete and associated with Pleistocene fauna. Geoarchaeological data demonstrate that the archaeological component was exposed until ~8,000 calbp on a relict eolian landscape before burial. No radiocarbon ages were obtained on either extinct or extant faunal material from the site, and the excavated portion of the geologic stratum containing the artifact assemblage is devoid of other datable organics. Therefore, no unequivocal conclusion can be reached about the association of the extinct faunal material with the Suwannee artifacts. However, multiple lines of evidence fail to reject the hypothesis that the Ryan‐Harley lithic assemblage represents a single occupation of Suwannee point makers. Multiple lines of evidence suggest that the Suwannee occupation of Ryan‐Harley most likely occurred during the Younger Dryas (~12,900–11,700 calbp).

佛罗里达州赖安·哈雷古印第安人遗址的地球考古调查(8JE1004):瓦格萨河流域在更年轻的树妖时期对人类居住的影响

位于北佛罗里达州Wacissa河中的Ryan‐Harley(8JE1004)是美国东部为数不多的在埋葬环境中包含未排屑的披针形点成分(Suwannee)的地点之一。在美国东南部,在赖安-哈雷的Suwannee文物层中发现的灭绝和灭绝动物区系残留物被认为是更新世动物区系的证据。2015年,进行了考古考古发掘以确定Ryan-Harley Suwannee组合在文化上是否离散并且与更新世动物群相关。地质考古数据表明,埋葬前考古遗址一直暴露在约8,000 calbp的遗迹风化景观上。该地点的灭绝或现存动物材料均未获得放射性碳年龄,包含人工制品组合的地质地层的开挖部分不含其他易碎有机物。因此,关于灭绝的动物材料与Suwannee人工制品的关联,没有明确的结论。但是,有许多证据不能拒绝Ryan-Harley石器组合代表Suwannee制点人的一个职业的假设。多条证据表明,Suwannee占领Ryan-Harley的可能性很大,发生在年轻的树妖(约12,900–11,700 calbp)期间。多条证据无法拒绝Ryan-Harley石器组合代表Suwannee点制造商的单一占领这一假设。多条证据表明,Suwannee占领Ryan-Harley的可能性很大,发生在年轻的树妖(约12,900–11,700 calbp)期间。多条证据无法拒绝Ryan-Harley石器组合代表Suwannee点制造商的单一占领这一假设。多条证据表明,Suwannee占领Ryan-Harley的可能性很大,发生在年轻的树妖(约12,900–11,700 calbp)期间。
