Lime Powder Production in the Maya Puuc Region (A.D. 600–950): An Experimental Pit-Kiln

Powdered lime was one of the most significant materials in the daily lives of the Prehispanic Maya, yet archaeologists have uncovered relatively little evidence of production methods or locales prior to the Spanish conquest. The recent identification of a series of pit-kilns dating to the Late and Terminal Classic periods (ca. a.d. 650–950) in and around the site of Kiuic in the Puuc region of the northern lowlands of the Yucatán Peninsula provides the opportunity to investigate a sub-regional Prehispanic lime production technology. Here we present the preliminary excavation results of nine pit-kilns and then describe the experimental reconstruction and firing of a lime pit-kiln. The results indicate that the pit-kilns are more fuel-efficient than the aboveground pyres used during the post-conquest period. This in turn suggests that Prehispanic inhabitants of the Puuc managed their consumption of natural resources for producing lime during a period of sociopolitical, demographic, and environmental stresses.     

Building a high-resolution chronology at the Maya archaeological site of El Palmar,Mexico

This paper discusses how detailed analyses of archaeological contexts and macrobotanical remains are critical for building a high-resolution chronology in archaeological research. While the application of Bayesian modelling has improved chronology-building significantly, archaeologists have sometimes neglected different dates recovered from the same depositional layer without further scrutiny. Based on 78 radiocarbon samples, this problem is challenged by building a high-resolution chronology of the Guzmán Group, a small plaza compound of the ancient Maya city of El Palmar, Mexico. The results permit a deeper understanding of relationships between dynastic interactions and the emergence of non-royal elites in Classic Maya society.     

半坡“人面衔鱼”图案再分析

半坡"人面衔鱼"图案表现的是一条俯视视角下的鱼,而非戴有装饰的人,应定名为"人面鱼"纹。对观者来说,它是"对视"和"远观"两种视角的结合,其设计目的在于通过二维的方式表现三维场景。参考玛雅文明关于地下水世界和人化鱼重生的观念,依据此类图形的出土情境,我们推测它很可能表达了半坡人群希望部分死者能够转化为鱼,穿过象征死亡的水域,进而重生或转世的愿望。     

Architectural Energetics, Ancient Monuments, and Operations Management

Architectural energetics, subsumed within replicative archaeology, provides a means through which buildings are translated into labor-time estimates. To date, the majority of architectural energetics analyses have generated comparative measures of architectural costs, equating these with a vertical structure of political power and authority within and among societies. The present analysis expands the application of architectural energetics by subjecting construction labor costs to an analysis based on concepts central to the Theory of Constraints, which is widely applied in modern operations management. This modeling generates a hypothetical set of behavioral patterns performed by general laborers within a construction project and explicates a method which allows further exploration into the question of labor organization (i.e., allocation and articulation of workers), as well as perhaps other economic organization, in an archaeological context. The case example is Structure 10L-22, a large Mayan palace at the site of Copan, Honduras.     

What Maya Collapse? Terminal Classic Variation in the Maya Lowlands

Interest in the lowland Maya collapse is stronger than ever, and there are now hundreds of studies that focus on the era from approximately A.D. 750 to A.D. 1050. In the past, scholars have tended to generalize explanations of the collapse from individual sites and regions to the lowlands as a whole. More recent approaches stress the great diversity of changes that occurred across the lowlands during the Terminal Classic and Early Postclassic periods. Thus, there is now a consensus that Maya civilization as a whole did not collapse, although many zones did experience profound change.     

Past or present? Differentiating California prehistoric native American remains from forensic cases: An empirical approach

The goal of this project is to provide additional data and statistical analyses for differentiating between prehistoric/historic Native American remains and modern forensic cases that may be potentially confusing. Forensic anthropologists often receive requests from local law enforcement to infer whether skeletal remains are of forensic or non‐forensic significance. Skeletal remains of non‐forensic significance are commonly of Native American ancestry, but the empirical methods common for determining Native American affinity from skeletal remains have not been established for California prehistoric/historic Native Americans. Therefore, forensic anthropologists working in California lack empirical methods for not only identifying prehistoric California Native American remains, but also differentiating them from modern/forensic populations whose skeletal attributes are similar. In particular, skeletal remains of Latin American US immigrants of indigenous origins are becoming more present in the forensic anthropological laboratory, and can exhibit the same suite of skeletal traits classically used to identify Native American affinity. In this article, we initiate an investigation into this issue by analyzing both craniometric and morphoscopic data using a range of statistical methods for differentiating prehistoric Northern California Native Americans from modern Guatemalan Maya. Our discriminant analyses results indicate that by using nine craniometric variables, group classification is 87% correct. In addition, seven morphoscopic variables can predict group classification correctly for 77% of the sample. The results suggest that it is possible to differentiate between our two samples. Such a method contributes to the efficient and empirical determination of temporal and geographic affinity, allowing for the repartriation of Native American remains to their tribes, as well as the accurate analysis of forensically significant remains.

Chemical composition of architectural plaster at the Classic Maya kingdom of Piedras Negras,Guatemala

Architectural plaster from elite masonry structures at the Classic Maya kingdom of Piedras Negras, Guatemala, is examined. Chemical composition is determined through X-ray fluorescence and compared statistically. Based on this sample, it was observed that any single masonry building was coated with plaster made from a single source of limestone and limestone-based aggregate, but that architectural plaster from different buildings across the site varied in chemical composition. It is concluded that this pattern is best accounted for by a model of rotational labor obligations to the state, with spatially distinct groups being responsible for manufacturing plaster for specific buildings.     

Deciphering the inorganic chemical record of ancient human activity using ICP-MS: a reconnaissance study of late Classic soil floors at Cancuén,Guatemala

Inorganic chemical analysis of soil floors using inductively coupled plasma-mass spectrometry (ICP-MS) was undertaken to provide information on the nature and location of past human activity in the ancient Maya city of Cancuén, Guatemala. The use of ICP-MS to detect trace and ultra-trace elemental enrichment of two excavated soil floors from the late Classic period is the first study of its kind in Mesoamerican archaeology. Geochemical background of the site was established by the analysis of palaeosols and nearby undisturbed ‘off-site’ soil profiles. Robust statistical methods used in the study clearly distinguished the level of anthropogenic enrichment across the former floors. Many elements measured showed only minor departures (10–20%) from the site's background soil chemistry. The greatest levels of elemental enrichment were detected in the rare earth elements, mercury, and gold. The latter is of particular interest considering the consensus that gold was absent from the world of the Classic-period Maya. Comparisons of the spatial pattern of mercury enrichment with lithic and archaeological data show strong linkages to past industrial and ritual activities. Elevated rare earth element concentrations were recorded broadly across both soil floors and are considered to be related to concentrated human occupation in antiquity.     

A Filtered Past: Interpreting Salt Production and Trade Models from Two Remnant Brine-Enrichment Mounds at the Ancient Maya Paynes Creek Salt Works,Belize

The mounds at Witz Naab and Killer Bee are the only known remaining aboveground evidence of a once-thriving salt industry in Punta Ycacos Lagoon, a large saltwater system in Paynes Creek National Park, Belize. Over one hundred ancient Maya salt works dated to the Classic period (a.d. 300–900) have been submerged by sea-level rise in the lagoon. We have hypothesized that mounds were once numerous features on the landscape prior to a sea-level rise that occurred in the area during the Terminal Classic period. Lacking at these underwater sites are earthen mounds formed by discarded soil from the leaching process in which the salinity of seawater was enriched by leaching brine through salty soil. Enriching the salinity of seawater by leaching or by solar evaporation is virtually universal in ethnographic case studies. Data from the excavations are evaluated to interpret the ancient activities that produced the earthen mounds, scales of production, and how the coastal Maya of southern Belize participated in the larger Classic Maya economy.     

Country Roads: Travel,Visibility, and Late Classic Settlement in the Southern Maya Mountains

Mayanist archaeology has long been concerned with creating and evaluating explanatory models for the locations of ancient sites relative to one another and to the physical geography of the Maya world. This study combines epigraphic data and spatial analyses to explore motivations for settlement location and to interrogate territorial strategies in Late Classic (a.d. 600–830) kingdoms in the southern Maya Mountains, around the modern towns of Dolores and Poptún, Guatemala. Least-cost path analyses were used to model natural travel corridors and their relationship with site location was assessed. In conjunction, viewshed analyses were applied to evaluate the importance of visual connections to likely travel routes. The results are considered in the context of the socio-politics and economics of the region, and raise questions about the character of and interconnections between travel, exchange, settlement location, and mechanisms for reinforcing territorial claims in the Late Classic Southern Maya Mountains.
