Describing whisker morphology of the Carnivora
One of the largest ecological transitions in carnivoran evolution was the shift from terrestrial to aquatic lifestyles, which has driven morphological diversity in skulls and other skeletal structures. In this paper, we investigate the association between those lifestyles and whisker morphology. However, comparing whisker morphology over a range of species...Dougill, Gary ; Brassey, Charlotte A ; Starostin, Eugene L ; Andrews, Hayley ; Kitchener, Andrew C …

Narrow-beaked trogons from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK)
We describe multiple partial skeletons of a new trogon species from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK), which are among the oldest fossils of the Trogoniformes. , gen. et sp. nov. has a much narrower and more gracile beak than extant trogons, which denotes different ecological attributes...Mayr, Gerald ; De Pietri, Vanesa L ; Kitchener, Andrew C

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 …

A new fossil from the London Clay documents the convergent origin of a “mousebird-like” tarsometatarsus in an early Eocene near-passerine bird
We describe a partial skeleton of a small bird from the lower Eocene London Clay of Walton-on-the-Naze (Essex, UK), which shows close affinities to two phylogenetically controversial early Paleogene taxa, Morsoravis sedilis (lower Eocene of Denmark) and Pumiliornis tessellatus (lower/middle Eocene of Germany). Our phylogenetic analysis supports a clade including...Mayr, Gerald ; Kitchener, Andrew 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

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... -

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 …

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
