A study has found that high-latitude phytoplankton communities responded to a pre-PETM warming event, highlighting the importance of examining background intervals in determining ecosystem change. The results suggest even small environmental changes can have dramatic impacts on marine ecosystems.
Research by University of Texas Institute for Geophysics reveals how ancient global warming affected the Gulf of Mexico's marine life and chemistry. The study found that radiolarians thrived in the Gulf due to nutrient-rich river sediments, providing valuable lessons about current climate change.
Researchers have discovered three new species of ancient mammals in North America, hinting at rapid evolution following the mass extinction of dinosaurs. The creatures, which include the 'Hobbit'-named Beornus honeyi, differ from earlier known mammals and suggest that mammals diversified more rapidly than previously thought.
Fossil leaves from a sweet potato ancestor and the morning glory family, Convulvaceae, were discovered in northeastern India and dated to 58.7-55.8 million years ago. This finding suggests that the plant family originated in East Gondwana and diverged from its sister Solanaceae by the late Paleocene.
