Prehistory of the Jama River, Ecuador

James Zeidler博士和Deborah Pearsall博士将合作 在圣伊西德罗的现场实地考察的季节， 位于厄瓜多尔北方的贾马河流域。 他们将继续 在现场挖掘，并扩大他们的调查， 周边地区。 圣伊西德罗包含一个大型的， 发现了土丘，这表明它的功能是 区域礼仪和行政中心。 网站的大小 和纪念性建筑都意味着剩余的存在 能够支持密集人口的生产，以及 迄今发现的材料表明，圣伊西德罗是一个主要的 对外联系点和商品流都沿着海岸 位于厄瓜多尔的海岸和高地之间。 研究 考古队将在遗址内挖掘大块， 并确定它如何随着时间的推移而变化。 在其他地点继续进行勘测和试掘， 将这一模式推广到区域一级。 特别 重点将放在生存技术和尝试 将致力于农业系统的重建。 研究的目的是研究人口统计学的过程， 增长以及生存和伴随的变化 文化复杂性的发展，发生在这个 厄瓜多尔北方的热带地区。 虽然如此复杂 社会在热带地区兴起，很多时候，在不同的地方， 世界上，基本的过程没有得到很好的理解。 这项研究将允许测试不同的模型。 而 众所周知，厄瓜多尔拥有丰富的史前遗迹， 在那里进行了考古研究。 这个项目 将有助于纠正这种情况。

Drs. James Zeidler and Deborah Pearsall will collaborate for two seasons of fieldwork at the site of San Isidro which is located in the Jama drainage in northern Ecuador. They will continue to excavate at the site and also extend their survey of the surrounding region. San Isidro contains a large, centrally located earthen mound which suggests that it functioned as a regional ceremonial and administrative center. The site's size and monumental architecture imply the existence of surplus production capable of supporting a dense population, and materials recovered to date suggest that San Isidro was a major point of external contact and commodity flow both along the coast of Ecuador and between the coast and the highlands. The research team will excavate large blocks within the site to reconstruct settlement history and determine how it changed over time. Continued survey and test excavation at other sites will allow extension of this pattern to a regional level. Particular emphasis will be placed on subsistence technology and an attempt will be made to reconstruct the agricultural system. The goal of the research is to study the process of demographic growth as well as change in subsistence and the accompanying development of cultural complexity which took place in this tropical area of northern Ecuador. Although such complex societies arose in the tropics, many times, in different parts of the world, the underlying processes are not well understood. This research will allow the testing of different models. While Ecuador is known to be rich in prehistoric remains, little archaeological research has been conducted there. This project will help to remedy that situation.
