Abstract
Various osteological techniques can be used to assess the developmental age of an infant skeleton, but it is more difficult to discern whether an infant had died before or after birth. Histological analysis of bone microstructure to look for microbial tunnelling (bioerosion) by putrefactive gut bacteria may represent a novel method of determining whether an archaeological infant had been a live birth. Gut bacteria spread around the body in the days following death and are primarily responsible for the putrefactive stage of decomposition. Most archaeological human bones that have been looked at using this method have been extensively bioeroded by bacteria. However, around half of archaeological young infant human skeletons remain free from bacterial tunnelling. The infant gut microbiome is thought to develop soon after birth and the best explanation for the large proportion of unbioeroded archaeological young infant skeletons is that they represent the remains of stillborn and short-lived infants that had not yet developed their bioerosive gut bacteria. The ability to identify stillborn and short-lived infant skeletons in the archaeological record has useful applications to the study of demography, health and social belief towards infancy and the beginnings of life in past populations. This chapter will discuss the use of histological analyses of bone diagenesis to identify stillborn infants in the archaeological record and demonstrate how this method may be applied to specific archaeological questions.

Abstract Collagen isolated from archaeological bone is a common material for radiocarbon dating, stable isotope analysis, and zooarchaeology by mass spectrometry (ZooMS). However, not all bones contain extant collagen, leading to unnecessary destruction of unproductive bones and wasted laboratory time and resources. An aim of this research is to study bone diagenesis, particularly collagen destruction, in an effort to develop a minimally destructive method for identifying bones with high collage...

Summary The acquisition and development of the infant microbiome are key to establishing a healthy host-microbiome symbiosis. The maternal microbial reservoir is thought to play a crucial role in this process. However, the source and transmission routes of the infant pioneering microbes are poorly understood. To address this, we longitudinally sampled the microbiome of 25 mother-infant pairs across multiple body sites from birth up to 4 months postpartum. Strain-level metagenomic profiling showe...

An understanding of the structural complexity of mineralised tissues is fundamental for exploration into the field of diagenesis. Here we review aspects of current and past research on bone and tooth diagenesis using the most comprehensive collection of literature on diagenesis to date. Environmental factors such as soil pH, soil hydrology and ambient temperature, which influence the preservation of skeletal tissues are assessed, while the different diagenetic pathways such as microbial degradat...

Most histological analyses of bone diagenesis are destructive and limited to the inspection of a cross-section that may not be representative of the whole. X-ray microtomography (Micro-CT) may provide a non-destructive means of investigating taphonomically-significant diagenetic alterations throughout whole bone samples, but this method has not been tested systematically (Dal Sasso et al., 2014). Bacterial bioerosion is the most common form of diagenesis found in archaeological bones, yet a rece...

Sub-fossilised remains may still contain highly degraded ancient DNA (aDNA) useful for palaeogenetic investigations. Whether X-ray computed [micro-] tomography ([mu]CT) imaging of these fossils may further damage aDNA remains debated. Although the effect of X-ray on DNA in living organisms is well documented, its impact on aDNA molecules is unexplored. Here we investigate the effects of synchrotron X-ray irradiation on aDNA from Pleistocene bones. A clear correlation appears between decreasing a...

Bone is a highly specialised form of hard and rigid connective tissue whose histological structure undergoes post-mortem modifications. In taphonomic research, histological examination of bone thin sections is used to investigate these post-mortem microstructural changes in skeletal tissues. In this study, diagenetic modifications in pig skeletal remains (Sus scrofa domesticus) which were exposed to different taphonomic conditions as part of a long-term, real-time experiment were examined under ...

A central problem in funerary archaeology is interpreting how the corpse was manipulated in the immediate post mortem period. The extent of bacterial bioerosion to the internal bone microstructure has been proposed as a means to infer the early post mortem history of a corpse, as it has been suggested that this form of bone diagenesis is produced by an organism's putrefactive gut bacteria. Under this model, different forms of funerary treatment would be expected to leave characteristic signature...

Epidemiological research since the 1980s has highlighted the consequences of early life adversity, particularly during gestation and early infancy, for adult health (the “Barker hypothesis”). The fast-evolving field of molecular epigenetics is providing explanatory mechanisms concerning phenotypic plasticity in response to developmental stressors and the accumulation of disease risk throughout life. In addition, there is now evidence for the heritability of poor health across generations via epi...

Teeth are often the preferred source material for isotopic and genetic assay involving ancient biomolecules. The assumption is that dental tissue preserves better due to its anatomically protected location, the enamel cap, and lower porosity compared to bone. However, this assumption has not been widely tested. Some similarities in diagenetic processes are to be expected due to similarities in structure and chemical composition of dentine and bone. This has led to the suggestion that bone can be...
