Recent investigations at the Maya centre of Nakum (located in northeastern Guatemala) included intensive excavations of Structure X (a.k.a. Structure 104)-one of the largest pyramidal temples at this site. This research showed that the first major version of this building consisted of a three-terraced platform dated to the Middle Preclassic period (750-300 bc), which was part of an important complex, the so-called E-Group. Such groups constitute the oldest manifestation of monumental architecture in the Maya Lowlands. With time, Structure X was converted into a large pyramidal structure in which several burials were situated during the Classic period (ad 250-800), making it an important mausoleum with interments of important elite members of local society. One of these burials (no. 8) was discovered below the floor of the temple building located on top of the pyramid and was a richly equipped tomb. It is most likely the resting place of one of the Nakum kings reigning during the Early-Late Classic transition (c. ad 550-650). This tomb had 11 vessels, including beautiful examples of polychrome Maya ceramics (representing different supernatural beings), many marine materials, five stingray spines and other artefacts. The tomb chamber was also covered by a deposit consisting of several thousand flint flakes that most probably had some symbolic meaning. In this article we discuss ancient Maya burial customs as documented in Structure X and present it in a wider perspective. We also describe similar lithic deposits associated with some of the richest Lowland Maya tombs and present their meaning and symbolism. Resumen Las investigaciones recientes en el centro maya de Nakum (localizado en el Noreste de Guatemala) incluyeron excavaciones intensivas del Edificio X (también conocido como Edificio 104)-uno de los templos piramidales más grandes en este sitio. Los trabajos de investigación demostraron que la primera versión mayor de este edificio consistió en una plataforma de tres terrazas fechada para el período Preclásico Medio (750-300 a.C.), la que formaba parte de un complejo importante de edificaciones al que se denomina como tipo Grupo E. Este tipo de grupos constituyen la manifestación mas antigua de la arquitectura monumental en las Tierras Bajas Mayas. Con el tiempo, el Edificio X fue convertido en una piramide grande, en la cual durante el período Clásico (250-800 d.C.) fueron depositados varios entierros, lo que le convierte en un mausoleo importante que contiene sepulturas de los miembros de la elite local. Uno de estos entierros (No. 8) es una tumba con una rica

ABSTRACT Thousands of Neolithic and Bronze Age open-air rock art panels exist across the countryside in northern England. However, desecration, pollution, and other factors are threatening the survival of these iconic stone monuments. Evidence suggest that rates of panel deterioration may be increasing, although it is not clear whether this is due to local factors or wider environmental influences accelerated by environmental change. To examine this question, 18 rock art panels with varied art motifs were studied at two major panel locations at Lordenshaw and Weetwood Moor in Northumberland. A condition assessment tool was used to first quantify the level of deterioration of each panel (called “staging”). Stage estimates then were compared statistically with 27 geochemical and physical descriptors of local environments, such as soil moisture, salinity, pH, lichen coverage, soil anions and cation levels, and panel orientation, slope, and standing height. In parallel, climate modelling was performed using UKCP09 to assess how projected climatic conditions (to 2099) might affect the environmental descriptors most correlated with elevated stone deterioration. Only two descriptors significantly correlated (P < 0.05) with increased stage: the standing height of the panel and the exchangeable cation content of the local soils, although moisture conditions also were potentially influential at some panels. Climate modelling predicts warming temperatures, more seasonally variable precipitation, and increased wind speeds, which hint stone deterioration could accelerate in the future due to increased physiochemical weathering. We recommend key panels be targeted for immediate management intervention, focusing on reducing wind exposures, improving site drainage, and potentially immobilizing soil salts.

The Middle Mississippian component at Aztalan was a mixed, Late Woodland / Mississippian occupation sited within a heavily fortified habitation and mound center that is located on a tributary of the Rock River in Wisconsin. It represents the northernmost large Cahokian-related village recorded. The Oneota Lake Koshkonong Locality of the Rock River drainage is located approximately 20 km south of Aztalan, and it consists of a 25 km2 area along the northwest shore with a small cluster of habitation settlements. Sixty-eight radiocarbon measurements have been obtained from Aztalan, and 52 from Oneota settlements in the Lake Koshkonong Locality. We discuss how to best interpret this dataset, and we use Bayesian chronological modeling to analyze these dates. The results suggest that (1) Aztalan's Late Woodland (Kekoskee phase) occupation began in the AD 900s or early AD 1000s, (2) Aztalan's Mississippian occupation ceased in the AD 1200s, (3) Oneota occupations at Lake Koshkonong ...
