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.

Tracing holotype trajectories: Mapping the movement of the most valuable herbarium specimens

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1304-1321, July 2026.
Global efforts to protect biodiversity depend on fair access to key plant specimens. This study examines the distribution of 119,361 holotypes—unique herbarium specimens used to formally describe new plant species. By linking collection and storage data, we found that holotypes are increasingly held closer to their places of origin, particularly in ...
