New Basal Interatheriidae (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile [PDF]
American Museum Novitates, 2006 Abstract Two new basal interatheriids (“notopithecines”) are described from central Chile. Specimens of a new taxon, Johnbell hatcheri, derive from Abanico Formation deposits near Termas del Flaco, in the valley of the Rio Tinguiririca, forming a distinctive element of the Tinguiririca Fauna.

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.

The Initial Opening of the Drake Passage Occurred During ca. 62‐59 Ma
Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.Abstract Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula. Here, new zircon U‐Pb geochronological studies are conducted on the Barchans Islands, providing a critical age ...

Applied Vegetation Science, Volume 28, Issue 1, January/March 2025.We show that excluding native grazers from a South American grassy ecosystem leads to strong declines in plant species richness over an 18‐month period. Our results imply that severely defaunated South American ecosystems have retained plant taxa and functional trait complexes that can tolerate intense herbivory, identifying herbivore reintroductions ...
