Summary

Paleontologists Discover Fossils

Brazilian paleontologists found a fossilized canine from a large proborhyaenid sparassodont in the Tremembé Formation, dating 29–21 million years ago.
The find enhances understanding of carnivorous metatherians in South America during the Oligocene.
In Uruguay, researchers identified a Pleistocene vulture likely representing a new lineage related to modern vultures, suggesting it fed on glyptodonts.
Together, these discoveries contribute to the evolving narrative of South American prehistoric ecosystems.
