The bleached skeleton of a hundred-million-year-old Deinonychus can tell us a lot about what this dinosaur ate, how it ran, and even how it interacted with others of its kind, but not much about how long it lived before dropping dead of old age.

Answer: A decrease in photosynthesis would have affected all dinosaurs. A decline in plants would mean less food for plant-eating dinosaurs.
