Can Macroevolution Inform Contemporary Extinction Risk?
Ecology Letters, Volume 28, Issue 7, July 2025.We investigate the underlying assumptions of the idea that macroevolutionary indicators for large groups of species, such as rates of extinction, diversification or niche evolution, can inform species' current and future extinction risk status. We find that only past extinction rates can be reliable predictors of current extinction risk as the same ...

Palaeontology, Volume 68, Issue 4, July/August 2025.Abstract Taphonomic studies of Cenozoic mammals are scarce. We report a study of the taphonomy of the Corralito site (Middle Pleistocene to Holocene), Córdoba Province, Argentina, which documents the last population of the South American native ungulate typotherid Mesotherium cristatum. We discovered two specimens of M.

Tectonics, Volume 44, Issue 6, June 2025.Abstract The Shkoder‐Peja transverse zone (SPTZ) of Northern Albania marks the boundary between the Dinarides and Albano‐Hellenides and is marked by a ∼100 km SW‐ward shift of the ophiolitic nappe front. The SPTZ has been variably interpreted as a paleogeographic inheritance, a dextral strike‐slip fault, the hinge of the clockwise (CW) rotating Albano ...
