Se presentan los resultados de las investigaciones llevadas a cabo en dos sitios del Holoceno medio ubicados en la cuenca superior del Río Loa (norte de Chile), conocidos como Alero Huiculunche y Corte de La Damiana. Los trabajos desarrollados incluyeron excavaciones estratigráficas, obtención y análisis de dataciones radiocarbónicas y análisis del material lítico y arqueofaunístico recuperado. Las dataciones obtenidas hicieron posible desarrollar un modelo cronológico bayesiano, el que permite definir los límites temporales más probables de ocupación para cada asentamiento y para sus unidades estratigráficas. La ocupación de Alero Huiculunche se muestra más temprana que en Corte de La Damiana, si bien el modelo revela alta probabilidad de una coexistencia breve entre las poblaciones de ambos sitios. Los análisis líticos y arqueofaunísticos sugieren que se trata en ambos casos de campamentos base de ocupación reiterada pero posiblemente intermitente, con ocupaciones menos intensas y/o recurrentes en Alero Huiculunche en relación con Corte de La Damiana. El conjunto de evidencias apunta a la existencia de un proceso de intensificación económica creciente entre aproximadamente 8000 y 5500 cal aP, el cual decanta en un sistema de asentamiento de mayor estabilidad y densidad ocupacional, en especial a partir de 6500 cal aP.
介绍了在智利北部洛阿河上游的两个中全新世遗址进行的研究结果,这两个遗址被称为阿莱罗·韦库伦切和科尔特·德拉达米亚纳。开展的工作包括地层挖掘、放射性碳年代的获取和分析以及对回收的石器和考古材料的分析。获得的年代使开发贝叶斯年代学模型成为可能,该模型可以确定每个定居点及其地层单位最可能的占用时间限制。Alero Huiculunche的入住时间比Corte de la Damiana早,尽管该模型揭示了两个地点的人口之间短暂共存的高可能性。石器时代和考古分析表明,在这两种情况下,它们都是反复但可能是间歇性占领的基本营地,与Damiana法院相比,Huiculunche屋檐的占领强度较小和/或反复发生。这一系列证据表明,经济集约化进程正在增加,约为8000至5500卡尔·阿普,这导致了一个更稳定和职业密度更高的定居点系统,特别是从6500卡尔·阿普开始。

Using data from several well-preserved pyres, which are rarely found well preserved in the southwestern United States and northern Mexico, we examine cremation customs and their associated pyrotechnologies at the site of Cerro de Trincheras in northern Sonora, Mexico, from AD 1300 to 1450/1500. We explore variations in pyre construction and use, thermal alterations of the deceased, the deceased individuals’ biological profiles, the performance of mortuary rituals, and the sensorial experiences of both the mourners and the wider Cerro de Trincheras community. The residents of the site were masters of the pyrotechnologies associated with cremations, making efficient pyres for the deceased and maximizing their resources. The group also created transformative funeral rituals that may have facilitated and mediated a wide range of emotional responses toward their deceased.
利用美国西南部和墨西哥北部很少发现的几个保存完好的柴堆的数据,我们研究了公元1300年至1450/1500年墨西哥索诺拉州北部Cerro de Trincheras遗址的火葬习俗及其相关的烧制技术。我们探索了柴堆结构和使用的变化、死者的热变化、死者个人的生物特征、太平间仪式的表现,以及哀悼者和更广泛的Cerro de Trincheras社区的感官体验。该遗址的居民掌握了与火葬相关的火葬技术,为死者制作了高效的火葬柴堆,并最大限度地利用了他们的资源。该组织还创造了变革性的葬礼仪式,这些仪式可能促进和调解了对死者的广泛情感反应。

En este trabajo se discuten las estrategias de explotación de ungulados por parte de los grupos cazadores-recolectores que habitaron los sectores ecotonales del Parque Nacional Perito Moreno (Santa Cruz, Argentina). La importancia del guanaco (Lama guanicoe) y el huemul (Hippocamelus bisulcus) en la subsistencia de estos sectores precordilleranos se mantuvo constante desde la transición Pleistoceno/Holoceno. La muestra analizada corresponde a un basural datado en el Holoceno medio (ca. 5500 años aP) perteneciente al sitio Cerro Casa de Piedra 7. La variedad de partes anatómicas, junto con la diversidad y frecuencia de marcas de procesamiento, da cuenta de un aprovechamiento integral e intensivo de ambas especies. La explotación del guanaco se habría centrado, principalmente, en grupos familiares con una marcada selectividad de individuos en edad reproductiva. El incremento demográfico en las poblaciones de guanacos ocurrido durante el Holoceno medio, tal como señalan investigaciones moleculares en Patagonia, habría permitido esta interacción predador-presa sin consecuencias ecológicas negativas. En tanto, el huemul tuvo un rol complementario en la dieta y su obtención se basó en una estrategia de caza oportunista, sin causar una presión predatoria significativa sobre esta presa. Las discrepancias en el aprovechamiento responderían a cuestiones etológicas y demográficas propias de estos ungulados.
本文讨论了居住在佩里托·莫雷诺国家公园(阿根廷圣克鲁斯)生态区的狩猎-采集群体对有蹄类动物的开发策略。自更新世/全新世过渡以来,瓜纳科(Lama Guanicoe)和胡穆尔(海马bisulcus)在这些前寒武纪部门生存中的重要性一直保持不变。分析的样本对应于Cerro Casa de Piedra 7遗址的中全新世(约公元前5500年)的一个垃圾场。解剖部位的多样性,加上加工标记的多样性和频率,实现了两个物种的全面和集约利用。瓜纳科的开发主要集中在对育龄个体有明显选择性的家庭群体上。正如巴塔哥尼亚的分子研究所指出的那样,在中全新世期间,瓜纳科斯种群的人口增加将允许这种捕食者-猎物的相互作用,而不会产生负面的生态后果。与此同时,Huemul在饮食中起着补充作用,其获得是基于机会主义的狩猎策略,而不会对这只猎物造成重大的捕食压力。利用方面的差异将解决这些有蹄类动物特有的行为学和人口问题。

Se analizan los microrrestos biosilíceos recuperados en el sitio Fuerte Sancti Spiritus, primer asentamiento español que se estableció en la cuenca del Río de la Plata en el período de la colonización y conquista europea en América. Está emplazado en Puerto Gaboto, provincia de Santa Fe, Argentina, y consiste en una ocupación breve que se produjo entre mayo de 1527 y septiembre de 1529. La excavación se realizó de acuerdo con la metodología open area, por lo cual el muestreo estuvo distribuido en diferentes rasgos localizados en la planta del emplazamiento. Se analizaron 20 muestras según dos variables: tipo de rasgo y cronología, lo que permitió establecer que se cultivaba maíz, junto con trigo y probablemente cebada, introducidos, concordante con las fuentes etnohistóricas. El análisis permitió, también, estimar el contenido de los rasgos de acuerdo con el sedimento muestreado, posibilitando la caracterización de zonas de descarte, rellenos, niveles de uso y sedimento acumulado con posterioridad al abandono del asentamiento.

Shark remains are common in coastal archaeological sites in southern Brazil. Here we present an analysis of microwear visible on shark teeth found at the Rio do Meio site in Florianópolis, Brazil. It demonstrates that hafted shark teeth were used to work soft materials such as leather, as well as semihard materials such as wood and bone, whereas others probably functioned as arrowheads. The results also show a possible preference for tiger shark teeth use for woodworking. The identified technical motions include piercing, cutting, and scraping, as well as scaling and sawing. These findings allow us to question the common interpretation of shark teeth use as ornaments and as having symbolic value. Instead, shark teeth seem to have been used as tools and weapons in daily life.
鲨鱼遗骸在巴西南部的沿海考古遗址中很常见。在这里,我们对在巴西Florianópolis的Rio do Meio遗址发现的鲨鱼牙齿上可见的微磨损进行了分析。研究表明,有轴的鲨鱼牙齿用于加工皮革等软材料,以及木材和骨头等半硬材料,而其他牙齿可能起到箭头的作用。研究结果还表明,人们可能更喜欢将虎鲨的牙齿用于木工。确定的技术动作包括穿孔、切割和刮擦,以及缩放和锯切。这些发现使我们能够质疑鲨鱼牙齿用作装饰物和具有象征价值的普遍解释。相反,鲨鱼的牙齿似乎被用作日常生活中的工具和武器。

The Napo River basin, which is situated within the Upper Amazon archaeological region, is one of the most speciose forests in Greater Amazonia. Standard thinking in scholarship and science holds that these forests are essentially pristine because any Indigenous impacts in the past would have been minimal, seedbanks would have been nearby, and natural forests would have reappeared after the humans left, died out, or dispersed. Inventory research in 2019 on three ridgetop forests in Waorani territory inside the Curaray basin (which drains to the right margin of the Napo River) and a comparable inventory on one control site forest along the Nushiño River (also in the Curaray basin) show human impacts from about the late nineteenth century to about 1960; they occurred during the period of wartime among Waorani themselves and between Wao people and outsiders. The human impacts resulted in the high basal-area presence of two long-lived species with important Waorani cultural uses: cacao (Theobroma cacao L.) and ungurahua palm (Oenocarpus bataua Mart.). These species have high frequency and dominance values and do not occur in the control site, which is comparable in terms of elevation above the flood zone of the rivers in the sample. These findings mean that alpha diversity in the right margin sector (or south) of the Napo River basin cannot a priori be explained by reference to traditionally, biologically accepted patterns of ecological succession but may require knowledge of historical patterns of Indigenous land use and secondary landscape transformation over time due to human (specifically Waorani) impacts of the past.
