MACROFLORAL ANALYSIS AT THE CAWALIVANO SITE (12PE929), PERRY COUNTY, INDIANA

A total of 98 soil samples from arbitrary levels in 2-m x 2-m units and from features in the
southeast portion of Site 12PE929, the Cawalivano site, in Perry County, Indiana, were examined
for macrofloral remains. This area of the site contains two primary cultural horizons,
representing Middle Archaic and Late Archaic occupations. Archaeological investigation at this
site provides a unique opportunity to study early prehistoric lifeways in the Ohio Valley,
particularly how groups utilized this area over time. Macrofloral analysis is used to provide
information concerning plant resources exploited by the various occupants of the site,
contributing to paleoenvironmental reconstructions for the area and to an understanding of how
use of plant resources may or may not have changed throughout the time periods represented.

本次研究共采集98份土壤样品，样品采集自印第安纳州佩里县Cawalivano遗址（Site 12PE929）东南部区域的2米×2米发掘单元各层位，以及该区域内的考古遗迹，所有样品均针对大植物遗存（macrofloral remains）开展了检测分析。该遗址的该片区存在两层主要文化层，分别对应中阿契贝时期（Middle Archaic）与晚阿契贝时期（Late Archaic）的人类定居活动。针对该遗址的考古调查为研究俄亥俄河谷（Ohio Valley）地区的早期史前生计模式提供了独特契机，尤其有助于探讨不同时期人类群体对这片区域的利用方式演变。通过大植物遗存分析，可获取该遗址各时期定居者所开发利用的植物资源相关信息，既为该区域的古环境重建（paleoenvironmental reconstructions）提供数据支撑，也有助于理解不同时段内人类对植物资源的利用方式是否发生了变化。
