Abstract Climate’s influence on late Pre-Columbian (pre-1492 CE), maize-dependent Native American populations in the midcontinental United States (US) is poorly understood as regional paleoclimate records are sparse and/or provide conflicting perspectives. Here, we reconstruct changes precipitation source and seasonality local warm-season duration rainstorm events related to Pacific North pattern (PNA) using a 2100-year-long multi-proxy lake-sediment record from US. Wet climate reflecting...
ABSTRACT: Forensic anthropologists use a number of maceration techniques to facilitate skeletal analysis personal identity and trauma, but they may unwittingly eliminate valuable DNA evidence in the process. This study evaluated effect 10 methods on gross bone structure preservation ribs 12 pigs ( Sus scrofa ). A scoring system was applied evaluate ease resulting quality while purity quantified by optical densitometry analysis, followed polymerase chain reaction (PCR) amplification three...
Bioarcheology has made tremendous strides since the subdiscipline's inception, subsequent syntheses, standardization of data collection methods, and analytical advances ranging from molecular analyses through age-estimation biodistance. Concurrently, health adaptive success past populations have remained primary concerns. However, questions are routinely raised about lesions whether or not changing frequencies synonymous with increases decreases in stress, morbidity, overall health. These...
The current study seeks to determine if a sample of foragers, farmers, and pastoralists are distinguishable based on their dental microwear texture signatures.The included 719 individuals from 51 archeological sites (450 192 77 pastoralists). All were over age 12 sexes pooled. Using Sensofar® white-light confocal profiler we collected analysis (DMTA) data single first or second molar each individual. We leveled cleaned clouds following standard procedures analyzed the with Sfrax® Toothfrax®...
Abstract Drought has long been suspected as playing an important role in the abandonment of pre-Columbian Native American settlements across midcontinental United States between 1350 and 1450 CE. However, high-resolution paleoclimatic reconstructions reflecting local effective moisture (the ratio precipitation to evaporation) that are located proximity Mississippi period (1050–1450 CE) population centers lacking. Here, we present a 1600-year-long decadally resolved oxygen isotope (δ 18 O)...
Floodplain development, land-use, and flooding on the lower Ohio River are investigated with a 3100-year-long sediment archive from Avery Lake, swale lake Black Bottom floodplain in southern Illinois, US. In all, 12 radiocarbon dates show that Lake formed at 1130 BCE (3100 cal. yr BP), almost 3000 years later than previously thought, indicating is younger more dynamic estimated. Three subsequent periods of extensive land clearance were identified by changes pollen composition, corresponding...
Abstract Mississippian mounds in the south‐eastern and mid‐continental United States often contain multiple construction stages a diverse array of features. Investigating mound with excavation is expensive, logistically challenging, sometimes politically impossible. Three at Angel site (12VG1), village ( ca ad 1100–1450) lower Ohio River Valley, were investigated non‐invasive geophysical minimally invasive geoarchaeological methods. We compare efficacy two different ground‐penetrating radar...
ABSTRACT Geophysical survey and excavations from 2010–2016 at Lawrenz Gun Club (11CS4), a late pre-Columbian village located in the central Illinois River valley Illinois, identified 10 mounds, plaza, dozens of structures enclosed within stout hectare bastioned palisade. Nineteen radiocarbon ( 14 C) measurements were taken single entities wood charcoal, short-lived plants, animal bones. A site chronology has been constructed using Bayesian approach that considers stratigraphic contexts...
Abstract The presence and sources of pre-Columbian (before 1492 CE) lead (Pb) pollution in the midcontinental United States were investigated using geochemical Pb isotope analyses on sediment cores recovered from Avery Lake, a floodplain lake located directly adjacent to Kincaid Mounds archaeological site lower Ohio River, Illinois. Geochemical results indicate during Baumer (300 BCE 300 Mississippian (1150–1450 occupations, since 1800s. link processing use galena primarily southeastern...
Since its inception, skeletally based paleodemographic research has emphasized the utility of biocultural models for interpreting dynamic relationship between sociocultural and ecological forces accompanying demographic transitions shaping populations' health well-being. While transition associated with Neolithic Revolution been a common focus in bioarcheology, present study analyzes human skeletal remains from large 19th century cemetery central Indiana to examine population dynamics during...
Facial landmark placement is a key step in many biomedical and biometrics applications. This paper presents computational method that efficiently performs automatic 3D facial based on training images containing manually placed anthropological landmarks. After face registration by an iterative closest point (ICP) technique, visual analytics approach taken to generate local geometric patterns for individual points. These individualized are derived interactively user's initial pattern...
Rigid adherence to culture histories has masked important regional variability and limited questions regarding cultural diversity social dynamics during the Late Archaic in Northeast. Considering multiple subregional allows for innovative interpretations of hunter-gatherers. Analysis at Castle Gardens site serves as one case study challenging traditional culture-historic framework that describes relationship between Vestal Lamoka phases Allegheny Plateau region Northern Appalachians. The...
