关于占领巴西南部高地南部原热窝房屋村庄的问题，长期以来的一种看法是，这些地点代表着长期被遗弃和重新占领的循环。然而，这一假设是基于个别坑房的放射性碳测年数量不足。为了解决这个问题，我们进行了全面的AMS放射性碳测年和贝叶斯建模计划，在巴乔一号遗址(加州)的一号超大坑房进行了深度分层。公元1395年-1650年)，巴西圣卡塔利那州南坎波贝洛。1号楼的地层显示了12个保存完好的楼层，证明了占领动态的重大变化，其中包括5个完全烧毁的坍塌屋顶。放射性碳测年的结果使我们第一次了解了巴西南部高地上一座超大坑房的占领动态。贝叶斯模型表明，1号房子被占用了两个多世纪，没有证据表明主要时期被遗弃，这对之前的长期遗弃模型提出了质疑。此外，House 1的序列允许我们将陶瓷风格和石材技术的变化与绝对年代学联系起来。最后，我们可以提供新的证据，证明超大型国内构造的出现是南部原泽尔地区相对较新的现象。随着纪念性的坑房开始建造，小型坑房继续有人居住，这表明公元1000年后国内建筑的差异正在显现。我们的研究显示了对个体结构进行密集测年计划的重要性，以了解占领动态和遗址持久性，并挑战了长期以来的假设，即巴西南部高地是南美洲低地背景下边缘文化的家园。
A long held view about the occupation of southern proto-Jê pit house villages of the southern Brazilian highlands is that these sites represent cycles of long-term abandonment and reoccupation. However, this assumption is based on an insufficient number of radiocarbon dates for individual pit houses. To address this problem, we conducted a programme of comprehensive AMS radiocarbon dating and Bayesian modelling at the deeply stratified oversized pit House 1, Baggio I site (Cal. A.D. 1395–1650), Campo Belo do Sul, Santa Catarina state, Brazil. The stratigraphy of House 1 revealed an unparalleled sequence of twelve well preserved floors evidencing a major change in occupation dynamics including five completely burnt collapsed roofs. The results of the radiocarbon dating allowed us to understand for the first time the occupation dynamics of an oversized pit house in the southern Brazilian highlands. The Bayesian model demonstrates that House 1 was occupied for over two centuries with no evidence of major periods of abandonment, calling into question previous models of long-term abandonment. In addition, the House 1 sequence allowed us to tie transformations in ceramic style and lithic technology to an absolute chronology. Finally, we can provide new evidence that the emergence of oversized domestic structures is a relatively recent phenomenon among the southern proto-Jê. As monumental pit houses start to be built, small pit houses continue to be inhabited, evidencing emerging disparities in domestic architecture after AD 1000. Our research shows the importance of programmes of intensive dating of individual structures to understand occupation dynamics and site permanence, and challenges long held assumptions that the southern Brazilian highlands were home to marginal cultures in the context of lowland South America.
