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 …

Psittacopedids and zygodactylids: The diverse and species-rich psittacopasserine birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK)
The Daniels collection of fossil birds from the early Eocene London Clay of Walton-on-the-Naze (Essex, UK) contains multiple specimens of the Psittacopedidae and Zygodactylidae, which are here for the first time studied in detail. The Psittacopedidae include Parapsittacopes bergdahli, Psittacomimus eos, gen. et sp. nov., ?Psittacopes occidentalis, sp. nov., and...Mayr, Gerald ; Kitchener, Andrew C

Enigmatic vertebrate trackway from the Scalby Formation (Middle Jurassic) Yorkshire, United Kingdom, with discussion of archosaur and ‘mammal’ trace fossils
We describe a new and unusual vertebrate trackway from the Middle Jurassic Scalby Formation of the Cleveland Basin, Yorkshire, United Kingdom. The Enigmatic Burniston Trackway (EBT) is the first and only example of such a trackway known from this region. The best preserved EBT print, belonging to a pentadactyl tetrapod,...synapsid, Sederipes, Synaptichnium, Ravenscar Group, and Footprint

Hugh’s printing protégé becomes his publisher. The story of Alexander Strachan or Strahan, publisher of The Life and Letters of Hugh Miller
I am researching Hugh Miller’s unusual publishing arrangements, including the frequency with which his firm, Miller & Fairly, printed his books for their Edinburgh publishers before and after his death. The obvious exception is Peter Bayne’s family-approved The Life and Letters of Hugh Miller (1871), printed in London for Strahan...Taylor, Michael A

Pendraig milnerae, a new small-sized coelophysoid theropod from the Late Triassic of Wales
We describe a new small-bodied coelophysoid theropod dinosaur, Pendraig milnerae gen. et sp. nov, from the Late Triassic fissure fill deposits of Pant-y-ffynnon in southern Wales. The species is represented by the holotype, consisting of an articulated pelvic girdle, sacrum and posterior dorsal vertebrae, and an associated left femur, and...Spiekman, Stephan N F ; Ezcurra, Martín D ; Butler, Richard J ; Fraser , Nicholas C ; Maidment, Susannah C R

New linguliformean brachiopods from the lower Tremadocian (Ordovician) of the Brabant Massif, Belgium, with comments on contemporaneous faunas from the Stavelot-Venn Massif
Lower Ordovician brachiopod macrofaunas in Belgium (Avalonia) are seldom collected and studied due to the poor preservation of material. Here we describe a new fauna of linguliformean brachiopods from the Chevlipont Formation (lower Tremadocian) in the Brabant Massif. The fauna is of low diversity (at least three species belonging to...Candela, Yves ; Marion, Jean-Marc ; Servais, Thomas ; Wang, Wenhui ; Wolvers, Mark …

Combined visual and biochemical analyses confirm depositor and diet for Neolithic coprolites from Skara Brae
Coprolites (fossilized faeces) can provide valuable insights into species’ diet and related habits. In archaeozoological contexts, they are a potential source of information on human-animal interactions as well as human and animal subsistence. However, despite a broad discussion on coprolites in archaeology, such finds are rarely subject to detailed examination... -

Novel track morphotypes from new tracksites indicate increased Middle Jurassic dinosaur diversity on the Isle of Skye, Scotland
Dinosaur fossils from the Middle Jurassic are rare globally, but the Isle of Skye (Scotland, UK) preserves a varied dinosaur record of abundant trace fossils and rare body fossils from this time. Here we describe two new tracksites from Rubha nam Brathairean (Brothers’ Point) near where the first dinosaur footprint...dePolo, Paige E ; Brusatte, Stephen L ; Challands, Thomas J ; Foffa, Davide ; Wilkinson, Mark …

Additional sauropod dinosaur material from the Callovian Oxford Clay Formation, Peterborough, UK: evidence for higher sauropod diversity
Four isolated sauropod axial elements from the Oxford Clay Formation (Callovian, Middle Jurassic) of Peterborough, UK, are described. Two associated posterior dorsal vertebrae show a dorsoventrally elongated centrum and short neural arch, and nutrient or pneumatic foramina, most likely belonging to a non-neosauropod eusauropod, but showing ambiguous non-neosauropod eusauropod and...Holwerda, Femke M ; Evans, Mark ; Liston, Jeff
