The use of mortar and pestles has long been associated with acorn processing in California. Based on ethnographic and archaeological evidence, groundstone was used to process a multitude of resources, including small mammals. Twenty groundstone artifacts recovered from the Rock Camp Site in the San Bernardino Mountains were analyzed for protein residues using the crossover immunological electrophoresis (CIEP) method. Using previously obtained data from the Summit Valley, a comparative analysis was done to determine if processing small mammals on groundstone was a common occurrence throughout the San Bernardino Mountain region.

This thesis is a pilot study, designed to test and develop methods suitable for the study of Scandinavian flint spearhead functionality. The functionality of projectile and lithic point armament has not been studied for almost 30 years in Scandinavia. Meanwhile, methods used to analyse lithic projectiles have developed considerably. However, few of these methods are precise enough to be used in conjunction with Scandinavian stone technological analyses that emphasize the societal aspect of lithic points. Consequently, two methods were chosen that could provide data for Scandinavian research issues: 3D-scanning/continuum mechanical simulations and organic residue analysis. The methods were tested on 6 experimental spearheads. The continuum mechanical simulation generated both visual and numerical data that could be used to create precise functional-morphological descriptions. The data could also potentially be used for projectile point classification. The organic residue analysis revealed promising results for the use of an artefact and activity specific analysis, with a sequential extraction protocol. In unison, the results from both analyses could be used to reveal how spearheads were functionally designed and used in Stone Age Scandinavia, even though there are methodological and technological issues that need solving.

A number of charred surface residues, adhering to ceramic containers, were obtained from various coastal and inland sites in north-west Europe dating from the sixth to the fourth millennium cal bc. In order to investigate the use of these vessels and in particular to identify any marine products, the residues were subjected to carbon and nitrogen stable isotope analysis. Variation in carbon isotope ratios between different samples indicated that some vessels may have been used to process marine products. This analysis was corroborated by specific identification of aquatic products following structural and isotopic characterization of lipids extracted from selected samples.

Despite the variety of successful reports of the preservation, recovery, and identification of archaeological proteins in general, there are few positive reports regarding mass spectrometry-based identification of ceramic-bound proteins. In large part, this shortage is due to the lack of consideration for the unique taphonomic histories of such residues and, in general, methods development. Further, because negative results are rarely published, there is no baseline to which results can be compared. This paper attempts to address these challenges via a multi-pronged approach that uses mass spectrometry and complementary approaches to evaluate ceramic-bound protein preservation in both controlled, actualistic experiments, and in archaeological artifacts. By comparing the results obtained from protein-spiked, experimentally-aged ceramic to those obtained from both faunal and ceramic archaeological materials, an enhanced perspective on protein preservation and subsequent recovery and identification is revealed. This perspective, focusing on taphonomy, reveals why negative results may be the norm for ceramic artifacts when non-targeted methods are employed, and provides insight into how further method development may improve the likelihood of obtaining positive results.

This study aims to contribute to the field of paleoethnobotany in Florida archaeology by presenting a novel approach to chemical residue analysis using UV-vis spectroscopy. The project's main goals are to develop a spectroscopic method for analyzing ceramics to identify phytochemical residues and present the findings of chemical analysis applied to ceramics from the Cape Canaveral archaeological mitigation project (CCAMP). The study focuses on two sites, the Penny site (8BR158) and Burns site (8BR85) in Florida's Indian River region. While organic residue analysis (ORA) has been applied to various materials and regions, limited research ORA on has been conducted within Florida archaeology. This study presents this approach in a simple and comprehensive manner so that it may be replicated by archaeologists who may be novice in in photospectroscopic methods. The presence of caffeine in the context of Malabar Period sites can enhance our understanding of the Ais people's foodways and cultural practices in Cape Canaveral by showing the ritualistic and common day use of Black Drink made from Ilex vomitoria. By developing this specific analytical method and applying it to the pottery from CCAMP, the study has shed light on the past use of ceramics, as well as the plant resources utilized by the people of prehistoric Florida.

No / This study examines resinous deposits from the interior surfaces of sherds of imported Canaanite amphorae and locally produced bowls from the 18th Dynasty site of Tell el-Amarna, Egypt. Archaeological evidence indicates that the Canaanite amphorae were used for resin transport, whilst the bowls are associated with burning resin as incense. A number of characteristic triterpenoids identify all the resinous deposits from both vessel types as Pistacia spp. No other resins were observed and there was no evidence of mixing with oils or fats. The composition of the archaeological resins is more complex than that of modern pistacia resin, due to degradation and generation of new components. Experimental heating alters the relative abundance of the triterpenoid composition of modern pistacia resin. One component, the triterpenoid 28-norolean-17-en-3-one, is produced by such heating; however, an increase in its relative abundance in ancient samples is not matched by the archaeological evidence for heating. It is therefore not possible to use this component reliably to identify heated resin. However, additional unidentified components with a mass spectral base peak at m/z 453 have been associated with seven (out of 10) bowls and are not observed in resins associated with Canaanite amphorae. It is proposed that these components are more reliable molecular indicators of heating.

Gas chromatography-mass spectrometry (GC-MS) was used to separate and identify the lipid constituents preserved in the matrix of a BRB sherd. Lipid biomarkers were recovered including long-chain n-alkanes, n-alkenes, palmitic wax monoesters, fatty acids and n-alcohols characteristic of beeswax. In addition to two disaccharides, cholesterol and β-sitosterol as contaminants were retrieved by solvent soluble extraction from a number of different locations from the ceramic matrix of the analysed sherd.

Yes / Vast numbers of votive mummies were produced in Egypt during the Late Pharaonic, Ptolemaic, and Roman periods. Although millions remain in situ, many were removed and have ultimately entered museum collections around the world. There they have often languished as uncomfortable reminders of antiquarian practices with little information available to enhance their value as artefacts worthy of conservation or display. A multi-disciplinary research project, based at the University of Manchester, is currently redressing these issues. One recent aspect of this work has been the characterization of natural products employed in the mummification of votive bundles. Using gas chromatography–mass spectrometry and the well-established biomarker approach, analysis of 24 samples from 17 mummy bundles has demonstrated the presence of oils/fats, natural waxes, petroleum products, resinous exudates, and essential oils. These results confirm the range of organic materials employed in embalming and augment our understanding of the treatment of votives. In this first systematic initiative of its kind, initial findings point to possible trends in body treatment practices in relation to chronology, geography, and changes in ideology which will be investigated as the study progresses. Detailed knowledge of the substances used on individual bundles has also served to enhance their value as display items and aid in their conservation. / RCB is supported by a PhD studentship from the Art and Humanities Research Council (43019R00209).
