Now showing at the American Museum of Natural History, “The End of the Age of Dinosaurs” traces the mass extinction that closed the Cretaceous and cleared the way for mammal life to expand. Using fossil evidence and current research, it follows the chain from impact and environmental shock to long-term ecological change. Presented in a museum setting, it lands as a public science document for New York, where debates over climate, vulnerability, and deep time feel close to home. Its most pointed move is refusing easy villainy, emphasizing systems over spectacle.
