New postcranial remains from the Lealt Shale Formation of the Isle of Skye, Scotland, showcase hidden pterosaur diversity in the Middle Jurassic
The Early to Middle Jurassic transition was significant in pterosaur evolution, during which these volant reptiles exploded in diversity alongside dinosaurs and other animals. It has long been thought, however, that pterosaurs did not develop large wingspans until after the Jurassic, a notion challenged by the recent discovery of in...Jagielska, Natalia ; Challands, Thomas J ; O'Sullivan, Michael ; Ross, Dugald A ; Fraser, Nicholas C …

Historical Textile Dye Analysis Using DESI-MS
Desorption electrospray ionization mass spectrometry (DESI-MS) is an ambient mass spectrometry technique that shows great potential for the analysis of fragile heritage objects in situ. This article focuses on the application of a recently built DESI source to characterize natural dyestuffs in historical textiles and a presentation of initial imaging...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Not so hidden messages
The written word is a powerful and persuasive tool that can inspire and revolt in equal measure. Equally, jewellery has the power to spread messages and has been used for generations to declare an individual’s position of allegiance or defiance. By incorporating a message, slogan or symbol, a jewel becomes...Rothwell, Sarah

Pests or prey? Micromammal species within an ancient anthropic environment at the Norse settlement site of Tuquoy (Westray, Orkney)
Micromammals, like rodents and shrews, adapt rapidly to take advantage of new food sources, habitats and ecological niches, frequently thriving in anthropogenic environments. Their remains, often retrieved during archaeological investigations, can be a valuable source of information about the past environmental conditions as well as interspecies interactions and human activity....Romaniuk, Andrzej A ; Troalen, Lore G ; Bendrey, Robin ; Herman, Jeremy S ; Owen, Olwyn …

Collecting the nation in the museum of the Society of Antiquaries of Scotland, 1832–91
The sixty-year period from 1832 to 1891 was key to the development of the Society of Antiquaries of Scotland and its museum, during which time its collection was transferred to national ownership and greater emphasis began to be placed on social and cultural history. This article analyses acquisition data to... -

Seasonal Adaptation: Geographic Photoperiod–Temperature Patterns Explain Genetic Variation in the Common Vole Tsh Receptor
The vertebrate photoperiodic neuroendocrine system uses the photoperiod as a proxy to time the annual rhythms in reproduction. The thyrotropin receptor (TSHR) is a key protein in the mammalian seasonal reproduction pathway. Its abundance and function can tune sensitivity to the photoperiod. To investigate seasonal adaptation in mammals, the hinge... -

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 …

Development and Application of Desorption Electrospray Ionization Mass Spectrometry for Historical Dye Analysis
A desorption electrospray ionization (DESI) source was built and attached to a Bruker 7T SolariX FT-ICR-MS for the in situ analysis of 14 early synthetic dyestuffs. Optimization using silk and wool cloths dyed with rhodamine B concluded that when using a commercial electrospray emitter (part number: 0601815, Bruker Daltonik), a...Sandström, Edith ; Vettorazzo, Chiara ; Mackay, C Logan ; Troalen, Lore G ; Hulme, Alison N

Range-wide whole-genome resequencing of the brown bear reveals drivers of intraspecies divergence
Population-genomic studies can shed new light on the effect of past demographic processes on contemporary population structure. We reassessed phylogeographical patterns of a classic model species of postglacial recolonisation, the brown bear ( ), using a range-wide resequencing dataset of 128 nuclear genomes. In sharp contrast to the erratic geographical...de Jong, Menno J ; Niamir, Aidin ; Wolf, Magnus ; Kitchener, Andrew C ; Lecomte, Nicolas …

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
