Discussions on the relationships between human groups and the environment are recurring Archaeology topics around the world. In South America, there is a specific kind of archaeological site called “earthen mound”, locally known as “cerritos de indios” that is ethnically linked to the Charrua and Minuano groups. They mainly cover southernmost Brazil (state of Rio Grande do Sul), Uruguay, and northeast Argentina. The study of the formative processes of these sites and their relationship with former inhabitants reveal distinct morphological and cultural characteristics in the context of each earthen mound occurrence. Thus, palynological studies associated with interdisciplinary research are important tools for understanding the environmental, and cultural dynamics of mound-builders. Within this context, this study presents new data on the formative processes and role of southern Brazilian earthen mounds by combining palynological, sedimentological, and chemical analyses. The analyses were performed on the earthen mound PSG-02 and adjacent area sediments, located on the southernmost Brazilian coastal plain, in a wetland called Pontal da Barra, at the estuary of Patos Lagoon. It was possible establish some relationships between its ancient occupation and the environmental dynamics and identify the influence of numerous environmental factors on their social dynamics. The earthen mound PSG-02, dated between 1280 ± 20 and 1859 ± 29 years BP, would probably be in a multifunctional context and was strategically located for gathering of natural resources as well as a dwelling and a funerary monument. Our findings are fundamental for understanding the interactions between earthen mound communities and the environment, filling another behavioral evolution gap of particular past human groups.

巴西最南部第四纪沿海平原的考古学孢粉

关于人类群体与环境之间关系的讨论是世界各地反复出现的考古学主题。在南美洲,有一种特定的考古遗址叫做“丘”,在当地被称为“喜瑞都德印第奥斯”,即种族链接到CharruaMinuano组。它们主要覆盖巴西最南端(南里奥格兰德州),乌拉圭和阿根廷东北部。对这些遗址的形成过程及其与前居民的关系的研究表明,在每次土墩出现的情况下,它们都有独特的形态和文化特征。因此,与跨学科研究相关的古生物学研究是了解土墩建造者的环境和文化动态的重要工具。在此背景下,本研究通过组合孢粉学,沉积学和化学分析,提供了有关巴西南部土墩形成过程和作用的新数据。这些分析是在巴西最南端沿海平原上的一个土墩PSG-02和邻近地区的沉积物上进行的,该沉积物位于一个叫做Pontal da Barra的湿地中,在Patos泻湖的河口。有可能在其古老的职业与环境动力之间建立某种关系,并确定许多环境因素对其社会动力的影响。土丘PSG-02的历史可追溯至1280±20到1859±BP(英国年)之间,其位置可能是多功能的,地理位置优越,可用于收集自然资源以及住宅和a葬纪念碑。我们的发现对于理解土墩群落与环境之间的相互作用,填补特定过去人类群体的另一行为进化鸿沟至关重要。有可能在其古老的职业与环境动力之间建立某种关系,并确定许多环境因素对其社会动力的影响。土丘PSG-02的历史可追溯至1280±20到1859±BP(英国年)之间,其位置可能是多功能的,地理位置优越,可用于收集自然资源以及住宅和a葬纪念碑。我们的发现对于理解土墩群落与环境之间的相互作用,填补特定过去人类群体的另一行为进化鸿沟至关重要。有可能在其古老的职业与环境动力之间建立某种关系,并确定许多环境因素对其社会动力的影响。土丘PSG-02的历史可追溯至1280±20到1859±BP(英国年)之间,其位置可能是多功能的,地理位置优越,可用于收集自然资源以及住宅和a葬纪念碑。我们的发现对于理解土墩群落与环境之间的相互作用,填补特定过去人类群体的另一行为进化鸿沟至关重要。可能处于多功能环境中,并且在战略上位于收集自然资源以及住宅和er葬纪念碑的位置。我们的发现对于理解土墩群落与环境之间的相互作用,填补特定过去人类群体的另一行为进化鸿沟至关重要。可能处于多功能环境中,并且在战略上位于收集自然资源以及住宅和er葬纪念碑的位置。我们的发现对于理解土墩群落与环境之间的相互作用,填补特定过去人类群体的另一行为进化鸿沟至关重要。
