The material landscapes of Scotland’s jewellery craft, 1780-1914
During the long 19th century, Scotland was home to an established body of skilled jewellers who were able to access a range of materials from the country's varied natural landscape: precious gold and silver; sparkling crystals and colourful stones; freshwater pearls, shells and parts of rare animals. Following these materials...Laurenson, Sarah

A new long‐necked archosauromorph from the Guanling Formation (Anisian, Middle Triassic) of southwestern China and its implications for neck evolution in tanystropheids
A long neck is an evolutionary innovation convergently appearing in multiple tetrapod lineages, including groups of plesiosaurs, non-archosauriform archosauromorphs, turtles, sauropodomorphs, birds, and mammals. Among all tetrapods both extant and extinct, two Triassic archosauromorphs, Tanystropheus and Dinocephalosaurus, have necks that are particularly elongated relative to the lengths of their trunks....Wang, Wei ; Spiekman, Stephan N F ; Zhao, Lijun ; Rieppel, Olivier ; Scheyer, Torsten M …

Evolutionary trends in trimerellid brachiopods
Non-articulated trimerellides, one minor group among the largest brachiopods, are commonly found in massive monospecific accumulations in Ordovician and Silurian rocks. In this paper, all species of the family Trimerellidae are listed for the first time, and some of them are discussed. They appeared in the Sandbian and became extinct...Chen, Di ; Huang, Bing ; Candela, Yves

Revision of the Llandovery (lower Silurian) trimerellide brachiopod Yidurella in South China
Although a minor group of brachiopods in the Ordovician and Silurian, the trimerellides include some of the largest known brachiopods in the Early Paleozoic. Yidurella Zeng, a monospecific genus of moderate size from the Shamao Formation of Tizikou, Yidu City, Hubei Province, was originally described as having a solid platform....Chen, Di ; Huang, Bing ; Candela, Yves

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 …

Objects in Place: the Eynhallow Sound, Orkney
Stone steps washed with waves and selkie songs glitter in the late summer gloaming. Roaring tides sweep in from all sides to batter the shore with ageless determination, steadily devouring the remnants of cairn-raisers, Picts, Norse, and crofters with equal indifference. The west wind catches a string of hanging seashells...Weinczok, David C

Whit's in a name: Scottish connections to mineral names
In mineralogy, as in other natural sciences, there are strict rules on the naming of mineral species. The vast majority of minerals are named after a person or a place. Many of these names have strong Scottish connections, while others are a little less obvious. The naming of minerals. In...Davidson, Peter
