"Sauropods grew big by munching ‘superfoods’ with..." Topic

… sturdy beaks.

"How did sauropod dinosaurs, the biggest creatures ever to have thundered across Earth, bulk up to the weight of more than 10 African bull elephants on a spartan diet of prehistoric greens? Many herbivores today grow fat on energy-rich grasses, but these and other nutritious flowering plants didn't become common until near the end of the dinosaurs' reign. Now, researchers think they have glimpsed the answer: a surprisingly nutrient-rich plant that could have been a mainstay of these dinosaurs' diets, and turtlelike beaks that buttressed sauropods' peglike teeth as they relentlessly stripped foliage from plants.

"We are seeing that they were able to acquire large volumes of food rapidly, and possibly nutrient-rich food," says Stephen Poropat, a paleontologist at Swinburne University in Melbourne, Australia.

Researchers at the University of Bonn in Germany presented the findings last week at the annual meeting of the Society of Vertebrate Paleontology here. Their previous work helped show that sauropods were eating machines that gulped down vegetation without chewing. They swung their long necks over vast areas, like prehistoric lawn mowers, while saving energy by keeping their bodies in one spot. The new studies add detail by exploring the beasts' diet and jaw structure…"
