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

open access: yesJournal 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.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...
