Raman spectroscopy of coloured resins used in antiquity: dragon's blood and related substances
Dragon's blood is a deep red resin which has been used for centuries by many cultures and much prized for it's rarity, depth of colour and alchemical associations. The original source of dragon's blood resin is believed to be Dracaena cinnabari from Socotra in Africa, but since mediaeval times there...Edwards, Howell G M ; de Oliviera, Luiz Fernando C ; Quye, Anita

‘Dragon’s Blood’ I—characterization of an Ancient resin using Fourier transform Raman spectroscopy
Several resins generically known as ‘dragon’s blood’ from different botanical and geographical sources were characterised non‐destructively using Fourier transform Raman spectroscopy. Genuine ‘dragon’s blood’ resin (Dracaena spp.) as found on Socotra Island was the probable source in antiquity. The spectra of recently collected Socotran resins from different sites were compared...Quye, Anita ; Edwards, Howell G M ; Farwell, D W

Mummy 1911-210-1
n ancient Egyptian mummy from the collections of the National Museums of Scotland was examined using computerised tomography (CT) scanning as part of the NMS mummy project. A facial reconstruction was produced from the CT scans for comparison with a painted 'portrait' which covers the face of the wrappings. The...Macleod, R I ; Eremin, Katherine ; Wright, A R ; McDonald, J

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

Ancient genomes indicate population replacement in Early Neolithic Britain
The roles of migration, admixture and acculturation in the European transition to farming have been debated for over 100 years. Genome-wide ancient DNA studies indicate predominantly Aegean ancestry for continental Neolithic farmers, but also variable admixture with local Mesolithic hunter-gatherers. Neolithic cultures first appear in Britain circa 4000 bc, a millennium after...Brace, Selina ; Diekmann, Yoan ; Booth, Thomas J ; Faltyskova, Zuzana ; Rohland, Nadin …

Effect of organic acid vapors on the alteration of soda silicate glass
Organic acids were previously shown to be involved in the alteration of historic soda silicate glasses in humid atmospheres under museum storage conditions. The present study investigates the role of these pollutants on the visual, compositional and structural modification of soda silicate glasses. Replica glasses aged in humid or humid/acidic... -

The use of Raman spectrometry to predict the stability of historic glasses
In the National Museums of Scotland (NMS) widespread alterations have been observed in the glass collections of 19th to 20th century, affecting British, Islamic and Asian glasses. It is important for museums to be able to distinguish between stable and unstable glasses, so that particular care can be taken to...Robinet, L ; Eremin, Katherine ; Coupry, Claude ; Hall, Christopher

New theropod dinosaur teeth from the Middle Jurassic of the Isle of Skye, Scotland
The Middle Jurassic is a largely mysterious interval in dinosaur evolution, as few fossils of this age are known worldwide. In recent years, the Isle of Skye has yielded a substantial record of trackways, and a more limited inventory of body fossils, that indicate a diverse fauna of Middle Jurassic...Young, Chloe M E ; Hendrickx, Christopher ; Challands, Thomas James ; Foffa, Davide ; Ross, Dugald A …

Raman investigation of the structural changes during alteration of historic glasses by organic pollutants
The combination of an unstable glass composition, fluctuating humidity and a high concentration of organic pollutants is responsible for the widespread alteration of part of the glass collections of the National Museums of Scotland (NMS). The alteration has resulted in the formation of crystalline corrosion at the surface and strong...Robinet, L ; Eremin, Katherine ; Coupry, Claude ; Hall, Christopher

Appropriate and appropriated sites for elephants: a case study of the making of museum objects
Through a case study of the museum career of a mounted specimen of African elephant, the nature of “museum objects” and sites in which they engage in the construction of meaning are examined. The paper tracks a series of representations through a museum and explores how this representative of the...Swinney, Geoffrey N

Three memoirs of Hugh Miller (1802–1856) by his son Hugh Miller FGS
Hugh Miller FGS (1850–1896) wrote a set of three memoirs on his father Hugh Miller (1802–1856), geologist, writer and newspaper editor. The first two are successive versions of a text written about 1883 to accompanya portrait of the elder Miller by the pioneering photographers David Octavius Hill (1802–1870)and RobertAdamson(1821–1848).The second...Taylor, Michael A

Revision of the Late Jurassic deep-water teleosauroid crocodylomorph Teleosaurus megarhinus Hulke, 1871 and evidence of pelagic adaptations in Teleosauroidea
Teleosauroids were a successful group of semi-aquatic crocodylomorphs that were an integral part of coastal marine/lagoonal faunas during the Jurassic. Their fossil record suggests that the group declined in diversity and abundance in deep water deposits during the Late Jurassic. One of the few known teleosauroid species from the deeper...Foffa, Davide ; Johnson, Michela M ; Young, Mark T ; Steel, Lorna ; Brusatte, Stephen L

A new hexactinellid sponge from the Silurian of the Pentland Hills (Scotland) with similarities to extant rossellids
The Pentland Hills sponge fauna (Llandovery, Telychian) consists of an unusual, aberrant assemblage, but of low diversity. A new specimen of a unique sponge, Eoghanospongia carlinslowpensis gen. et sp. nov., is described from the classic locality of R82. The mushroom-shaped, probably stalked body (peduncle attachment to body not exposed) resembles...Botting, Joseph P ; Candela, Yves ; Carrió, Vicen ; Crighton, William R B

Disentangling wing shape evolution in the African mayfly, Teloganodidae (Ephemeroptera)
Wings are one of the most important structures in the evolution of insects and winged insects are widely accepted as being monophyletic. In Ephemeroptera, wing structure and shape is important for interpreting taxonomic relationships. Morphological variation in wing shape of 14 distinct operational taxonomic units (OTUs) of South African Teloganodidae...Pereira-da-Conceicoa, Lyndall L ; Benítez, Hugo A ; Barber-James, Helen M
