The South American Archaeological Isotopic Database (SAAID) is a comprehensive open-access resource that aggregates all available bioarchaeological stable and radiogenic isotope measurements, encompassing data from human individuals, animals, and plants across South America. Resulting from a collaborative effort of scholars who work with stable isotopes in this region, SAAID contains 53,781 isotopic measurements across 24,507 entries from individuals/specimens spanning over 12,000 years. SAAID includes valuable contextual information on archaeological samples and respective sites, such as chronology, geographical region, biome, and spatial coordinates, biological details like estimated sex and age for human individuals, and taxonomic description for fauna and flora. SAAID is hosted at the PACHAMAMA community within the Pandora data platform and the CORA repository to facilitate easy access. Because of its rich data structure, SAAID is particularly well-suited for conducting spatiotemporal meta-analyses. It serves as a valuable tool for addressing a variety of research topics, including the spread, adoption, and consumption intensification of food items, paleo-environmental reconstruction, as well as the exploration of mobility patterns across extensive geographic regions.
南美考古同位素数据库（SAAID）是一个综合性的开放获取资源，它聚合了所有可用的生物考古稳定和放射性同位素测量数据，涵盖了来自南美的人类个体、动物和植物的数据。SAAID 是由在该地区研究稳定同位素的学者合作产生的，它包含了 53781 个同位素测量值，涉及 24507 个人/标本的条目，跨越了 12000 多年的时间。SAAID 包含了关于考古样本和相应地点的有价值的上下文信息，如年代学、地理区域、生物群落和空间坐标、人类个体的估计性别和年龄等生物学细节，以及动物群和植物群的分类描述。SAAID 托管在 Pandora 数据平台的 PACHAMAMA 社区和 CORA 存储库中，以便于访问。由于其丰富的数据结构，SAAID 特别适合进行时空荟萃分析。它是解决各种研究课题的有价值的工具，包括食物的传播、采用和消费强度的变化、古环境重建，以及探索广阔地理区域的流动模式。
