New data from Denmark confirm that some ammonite populations survived the Cretaceous–Paleogene boundary, with evidence suggesting both survival and redeposition depending on the microfacies and stratigraphic context, supporting the hypothesis that certain ammonites persisted into the Danian period.
A new study of fossils from New Mexico shows that dinosaurs were thriving just before the asteroid impact that caused their extinction, suggesting they were in good health prior to the catastrophic event. The fossils, dated to within 340,000 years of the impact, indicate a diverse and healthy dinosaur ecosystem in the region, supporting the idea that the asteroid abruptly ended their prosperity.
A fossil site known as the Cañadón Tomás Quarry in Argentina's Patagonia region is providing new insights into life at the end of the Cretaceous period. Excavations have uncovered numerous bones from hadrosaurs, as well as fossils from non-avian predatory dinosaurs, a snake, and a small mammal. The site has the potential to shed light on the biodiversity and evolution of Southern Hemisphere dinosaurs and contribute to our understanding of the Cretaceous-Paleogene boundary.
