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 …

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 …

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

The aspen hoverfly Hammerschmidtia ferruginea (Fallén)(Diptera, Syrphidae) in Deeside
After a gap of some 30 years the presence of the aspen hoverfly Hammerschmidtia ferruginea (Fallén, 1817), is confirmed in Deeside, Aberdeenshire. The methods used to re-establish the population are discussed.MacGowan, Iain

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... -

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 …
