Dinosaurs were thriving until asteroid struck, research suggests
Recent research suggests that dinosaurs were thriving before the asteroid impact that led to their extinction, challenging long-held beliefs that they were already in decline. By dating rock formations in New Mexico, scientists provide new insights into the late Cretaceous period, indicating that the catastrophic event was the primary cause of their demise. This finding is significant as it reshapes our understanding of dinosaur history and their ecological success prior to the mass extinction.
