Relative to the centuries preceding and following it, the tenth century a.d. in Mesoamerica is poorly understood by scholars. Although there is some regional variation in the timing of these events, archaeologists commonly ascribe a pattern of political decline, dynastic collapse, or social reorganization to this period. Paradoxically, increasing interregional interactions and emergent market exchange networks are also characteristics of macroregional patterns during the tenth century. These contradictory phenomena contribute to confusion surrounding interpretations of this transitional time. This article contributes a comparative dataset from systematic archaeological investigations of El Coyote, a monumental center in the lower Cacaulapa valley, Department of Santa Barbara, Honduras. The late occupational phase contains evidence for Early Postclassic chronological markers, including Tohil Plumbate pottery; obsidian from Pachuca, Hidalgo; and copper metallurgy. Calibrated radiocarbon assays with a 2σ error place these contexts between a.d. 710 and 1040, with a clustering of intercepts circa a.d. 900. These results are consistent with a pattern described throughout Mesoamerica and demonstrate that despite variation in the use of cultural terminology—Epiclassic, Terminal Classic, or Early Postclassic—there is uniformity in the timing of this macroregional interaction.

El Coyote、宏观区域交换和早期后经典中美洲

相对于它之前和之后的几个世纪来说，十世纪广告学者们对中美洲的了解甚少。尽管这些事件发生的时间存在一些地区差异，但考古学家普遍将政治衰落、王朝崩溃或社会重组的模式归因于这一时期。矛盾的是，不断增加的区域间互动和新兴的市场交换网络也是十世纪宏观区域格局的特征。这些矛盾的现象导致了对这一过渡时期的解释的混乱。本文提供了对 El Coyote 系统考古调查的比较数据集，El Coyote 是洪都拉斯圣巴巴拉省卡考拉帕山谷下游的一个纪念性中心。晚期职业阶段包含早期后古典时代标记的证据，包括托希尔铅酸盐陶器；产自伊达尔戈州帕丘卡的黑曜石；和铜冶金。校准的放射性碳测定具有 2σ 误差，将这些背景置于广告710 和 1040，大约有一组拦截广告900. 这些结果与整个中美洲所描述的模式一致，并表明，尽管文化术语（史诗、末期经典或早期后经典）的使用有所不同，但这种宏观区域相互作用的时间安排是一致的。
