The excavation of residential areas is a growing focus of research in Andean archaeology. Studies reveal that interpreting household remains from some prehispanic societies can be complex because of the nature of abandonment ritual, which may involve burnt offerings, the placement of valuables on floors, or the purposeful destruction of ceramic vessels that are distributed in patterned ways. The goods that constitute these offering practices can be confused with post-occupation refuse, especially when excavation units are relatively small. In this paper, I discuss the importance of assessing site formation processes in residential spaces and illustrate how different modes of household abandonment can make comparative analysis a complex exercise. I describe and compare several examples from Wari-affiliated residences at the sites of Cerro Baúl and Cerro Mejía, located in the department of Moquegua, Peru, to show how ritual depositions corresponding to house abandonment might affect the interpretation of daily domestic life. In particular, I examine how ritual assemblages have been interpreted as evidence of feasting to support propositions regarding the Wari political economy. I advocate that archaeologists interested in domestic areas, lifeways, and the political economy engage in large-scale horizontal excavations to ensure they can correctly distinguish between the remains of quotidian practices, the goods associated with ritual depositions, and refuse resulting from feasting, which is best substantiated with features and facilities to host empowering events.

Understanding the composition and diagenetic processes of the deposition environment is pivotal to understanding why bone undergoes preservation or diagenesis. This research explores the complex nexus of diagenesis at the extremes of preservation, via the interdependent chemical, and short- and long-term microbial processes that influence diagenesis. These processes include dissolution, ion exchange, hydrolysis, recrystallisation, waterlogging, acidity and alkalinity, soil composition, redox potential, bacterial activity, and microbiome composition. Diagenetic processes are discussed in relation to typical sites and sites with extremes of preservation. Understanding site conditions that impact diagenetic processes is critical to understanding the visual features presented in recovered skeletal material, ensuring an appropriate post-mortem interval is assigned, and for subsequent post hoc analysis of bone.

Traditional models of interaction in northern Sudan have innate Egyptological, elite, and urban biases which have relegated certain areas to mere peripheries of more ‘established’ and ‘central’ sites. In order to reach a higher resolution understanding of cultural dynamics and diversity of ancient Nilotic groups, the DiverseNile project has established the bespoke concept of Contact Space Biography which we present in the following article. We challenge existing approaches to cultural contact in the region by adopting a bottom-up approach which moves away from well-established categorisation of sites in our study area. In particular by reconstructing landscape biographies of the Bronze Age in the Middle Nile beyond established cultural categories in order to provide new insights into the ancient dynamics of social spaces, which include landscape features and non-human activities. In the following we instead consider such areas as complex social spaces intertwined with, an often changing, landscape by presenting our findings from the study of cemetery and settlement sites. Overall, the concept of Contact Space Biography effectively combines models of contact spaces, the idiosyncrasies of a changing landscape and the technological and industrial prerogatives of those living in and accessing this region.
