A newly discovered fossil feather offers rare insights into the evolutionary traits that may have helped certain bird species endure the catastrophic asteroid impact that wiped out the dinosaurs. Unlike many fossils from that era, this specimen remains remarkably intact, preserving details that could explain why some avian ancestors thrived while others perished. Researchers suggest its unique structure might hold clues about survival advantages tied to flight, insulation, or other critical adaptations. The find could reshape understanding of how birds emerged as the dominant land animals following one of Earth’s most devastating extinction events.
An extremely well preserved fossil feather could reveal why some birds survived the dinosaur-killing asteroid, and others did not.
