Exceptional Skull of Huayqueriana (Mammalia, Litopterna, Macraucheniidae) From the Late Miocene of Argentina: Anatomy, Systematics, and Paleobiological Implications [PDF]
Bulletin of the American Museum of Natural History, 2016 The Huayquerías Formation (Late Miocene, Huayquerian SALMA) is broadly exposed in west-central Argentina (Mendoza). The target of several major paleontological expeditions in the first half of the 20th century, the Mendozan Huayquerías ("badlands") have recently yielded a significant number of new fossil finds.

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 ...
