The braincase and inner ear of ‘Metriorhynchus’ cf. ‘M.’ brachyrhynchus–implications for aquatic sensory adaptations in crocodylomorphs
During their long evolutionary history crocodylomorphs achieved a great diversity of body sizes, ecomorphotypes and inferred feeding ecologies. One unique group of crocodylomorphs are the thalattosuchians, which lived during the Jurassic and Cretaceous (ca. 191–125 Ma). They transitioned from shallow marine species, like teleosauroids, into fully pelagic forms with paddle...Schwab, Julia A ; Young, Mark T ; Herrera, Yanina ; Witmer, Lawrence M ; Walsh, Stig A …

Cutting the Gordian knot: A historical and taxonomic revision of the Jurassic crocodylomorph Metriorhynchus
Metriorhynchidae was a clade of extinct crocodylomorphs that adapted to a pelagic lifestyle, becoming a key component of Mesozoic lagoonal and coastal marine ecosystems. The type genus Metriorhynchus is one of the best-known genera of Mesozoic crocodylomorphs, and since the mid-19th century, the ‘concept’ of Metriorhynchus has become associated with the referred species Me. superciliosus. Historically Metriorhynchus has...Young, Mark T ; Brignon, Arnaud ; Sachs, Sven ; Hornung, Jahn J ; Foffa, Davide …

Unwrapping the Galloway Hoard: Secrets of a unique Viking Age collection from south-west Scotland
Buried c.AD 900, the Galloway Hoard is thought to be Scotland's earliest-known Viking Age hoars. In the years since its discovery in 2014, wide-ranging research has illuminated its eclectic and often unique contents. As a new exhibition opens, exploring the story so far, Martin Goldberg takes us through some of...Goldberg, D Martin

Analysis of historical dyes in heritage objects, Analytical Methods Committee, AMCTB No. 101
Dye analysis can considerably enhance our understanding of the provenance of materials used in the production of historical objects. Knowledge of the individual constituents of any dyestuff not only facilitates its identification, but also provides important information regarding the rate of photo-degradation of the dye’s components; this can in turn...Troalen, Lore ; Hulme, Alison N

African and Asian leopards are highly differentiated at the genomic level
Leopards are the only big cats still widely distributed across the continents of Africa and Asia. They occur in a wide range of habitats and are often found in close proximity to humans. But despite their ubiquity, leopard phylogeography and population history have not yet been studied with genomic tools....Paijmans, Johanna L A ; Axel, Barlow ; Becker, Matthew S ; Cahill, James ; Fickel, Joerns …

Variation in predicted COVID-19 risk among lemurs and lorises
The novel coronavirus SARS-CoV-2, which in humans leads to the disease COVID-19, has caused global disruption and more than 2 million fatalities since it first emerged in late 2019. As we write, infection rates are at their highest point globally and are rising extremely rapidly in some areas due to...Melin, Amanda D ; Orkin, Joseph D ; Janiak, Mareike C ; Valenzeula, Alejandro ; Kuderna, Lukas …

Cetacean Skeletons Demonstrate Ecologically Relevant Variation in Intraskeletal Stable Isotopic Values
Conservation science requires quickly acquiring information and taking action in order to protect species at risk of extinction. Stable isotope measurements are one way to rapidly gather data regarding species’ foraging ecology and habitat use, and passively collected samples limit additional stress to at-risk species. For these samples to be...Smith, Kerri J ; Sparks, Jed P ; Timmons, Zena L ; Peterson, Markus J

A new phylogenetic hypothesis of Tanystropheidae (Diapsida, Archosauromorph) and other “prororosaurs” and its implications for the early evolution of stem archosaurs
The historical clade “Protorosauria” represents an important group of archosauromorph reptiles that had a wide geographic distribution between the Late Permian and Late Triassic. “Protorosaurs” are characterized by their long necks, which are epitomized in the genus Tanystropheus and in Dinocephalosaurus orientalis. Recent phylogenetic analyses have indicated that “Protorosauria” is a polyphyletic clade,...Spiekman, Stefan N F ; Fraser, Nicholas C ; Scheyer, Torsten M

High-quality carnivoran genomes from roadkill samples enable comparative species delineation in aardwolf and bat-eared fox
In a context of ongoing biodiversity erosion, obtaining genomic resources from wildlife is essential for conservation. The thousands of yearly mammalian roadkill provide a useful source material for genomic surveys. To illustrate the potential of this underexploited resource, we used roadkill samples to study the genomic diversity of the bat-eared...Allio, Rémi ; Tilak, Marie-Ka ; Scornavacca, Celine ; Avenant, Nico L ; Kitchener, Andrew C …
