Stone and earthen architecture is nearly ubiquitous in the archaeological record of Pacific islands. The construction of this architecture is tied to a range of socio-political processes, and the temporal patterning of these features is useful for understanding the rate at which populations grew, innovation occurred, and social inequality emerged. Unfortunately, this temporal patterning is poorly understood for many areas of the region, including the Sāmoan archipelago. Here, we describe a project directed toward establishing a robust chronology for the construction of these earthen and stone terraces and linear mounds on Ta‘ū Island. Using recent methodological improvements, we highlight the tempo at which different architectural types were constructed on the island and the implications for understanding demographic expansion and changing land tenure practices in the last 1500 years. This research suggests the construction of architecture was largely confined to the 2nd millennium AD with a small number of terraces plausibly built in the 1st millennium AD. This temporal patterning suggests that a reconfiguration of settlement patterns occurred within West Polynesia as people there moved into other regions of Oceania.

TA'Ū 岛上建筑景观的节奏和轨迹，MANU'A 集团，美国 SĀMOA：将广泛的放射性碳测年与联合后部建模相结合

石土建筑在太平洋岛屿的考古记录中几乎无处不在。该架构的构建与一系列社会政治进程相关联，这些特征的时间模式有助于理解人口增长、创新发生和社会不平等出现的速度。不幸的是，对于该地区的许多地区，包括萨摩亚群岛，人们对这种时间模式知之甚少。在这里，我们描述了一个项目，该项目旨在为在 Ta'ū 岛上建造这些土石阶地和线性土丘建立一个稳健的年表。使用最近的方法改进，我们强调了在岛上建造不同建筑类型的节奏，以及对了解过去 1500 年人口扩张和不断变化的土地使用权做法的影响。这项研究表明，建筑的建造主要局限于公元 2 世纪，少数梯田似乎建于公元 1 世纪。这种时间模式表明，随着人们迁移到大洋洲的其他地区，西波利尼西亚发生了定居模式的重新配置。
