Molecular fingerprints resolve affinities of Rhynie chert organic fossils
The affinities of extinct organisms are often difficult to resolve using morphological data alone. Chemical analysis of carbonaceous specimens can complement traditional approaches, but the search for taxon-specific signals in ancient, thermally altered organic matter is challenging and controversial, partly because suitable positive controls are lacking. Here, we show that...Loron , C C ; Rodriguez Dzul, E ; Orr, P J ; Gromov, A V ; Fraser, Nicholas C …

GLASS BANGLES IN THE BRITISH ISLES: A STUDY OF TRADE, RECYCLING AND TECHNOLOGY IN THE FIRST AND SECOND CENTURIES AD
Glass bangles are found in southern England and Wales from the mid-first century and become common in the north of England and southern Scotland in the late first century, before their numbers decline a century later. British bangles develop at a time of change, as Roman glassmaking practices were introduced...Paynter, Sarah ; Crew, Peter ; Campbell, Richard ; Hunter, Fraser ; Jackson, Caroline

Combined visual and biochemical analyses confirm depositor and diet for Neolithic coprolites from Skara Brae
Coprolites (fossilized faeces) can provide valuable insights into species’ diet and related habits. In archaeozoological contexts, they are a potential source of information on human-animal interactions as well as human and animal subsistence. However, despite a broad discussion on coprolites in archaeology, such finds are rarely subject to detailed examination... -

Non-destructive analysis of nineteenth century Scottish calotype negatives and salt prints
The combination of Raman spectroscopy and Secondary Ion Mass Spectrometry can improve understanding of the chemistry of the glass alteration process. Formic and acetic acids play an important role in the alteration of museum glass objects placed in a humid atmosphere. Raman spectroscopy indicates that the soda-rich glass structure is...Robinet, L ; Eremin, Katherine ; Fearn, Sarah ; Pulham, C ; Hall, Christopher

Conservation and analysis of deteriorating nineteenth and twentieth-century British glass in the National Museums of Scotland
The National Museums of Scotland collections includes about 2000 19th and 20th-century British glass artefacts. An initial conservation survey in 1996 identified 153 artefacts as actively deteriorating (Cobo del Arco 1999). Examinations of additional artefacts is ongoing and 212, c.20% of those surveyed to date, are deteriorating. The visible signs...Eremin, Katherine ; Cobo del Arco, B ; Robinet, L ; Gibson, L T
