Computed tomography reveals multiple origins of extreme caudal vertebral pneumaticity in sauropod dinosaurs

Journal of Anatomy, EarlyView.
Here, we present novel CT scan data of caudal vertebrae of six Middle–Late Jurassic sauropods, representing several eusauropod lineages. We synthesise these new data with a comprehensive critical appraisal of purported external and internal evidence for caudal vertebral PSP in Sauropodomorpha.

Un día en el Desierto de la Tatacoa [PDF]

Spatial and temporal evolution of a coastal erg margin: The Middle Jurassic Page Sandstone, southern Utah, USA

Sedimentology, Volume 73, Issue 6, Page 2081-2119, October 2026.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Controls of bulk density and grain size on Stage 1 evaporation from packed sand columns

Vadose Zone Journal, Volume 25, Issue 5, September/October 2026.
Abstract Soil evaporation from the vadose zone is strongly controlled by the pore size distribution and hydraulic connectivity, both of which are altered by mechanical compaction. However, the effect of bulk density changes and its vertical distribution on Stage 1 evaporation in sandy systems remains insufficiently quantified. In this study, we combine

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

International Journal of Urban and Regional Research, Volume 50, Issue 4, Page 960-981, July 2026.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.
