Dinosaurs may have been snacking on seaweed and other ocean foods more than 100 million years ago, according to surprising new evidence hidden in their fossilized teeth. Researchers discovered chemical signatures suggesting that coastal dinosaurs and other prehistoric animals relied partly on nutrients originating in the sea. The findings reveal that marine resources traveled through ancient food chains, supplementing the diets of everything from plant-eating dinosaurs to predators.
