- Engineering technology has revealed the eating habits of at least some giant plant-eating dinosaurs.
- Diplodocus, and possibly other sauropods, stripped leaves from branches and swallowed the plant material whole.
- Dinosaurs like Diplodocus may have had such small heads because they didn't chew their food.
Plant-eating dinosaurs 150 million years ago were super speedy eaters and could efficiently remove leaves from branches before swallowing the greenery whole.
The research, published in the journal Naturwissenschaften, helps to explain how some of the largest animals on Earth managed to eat such amazing quantities of plants.
The study focused in particular on Diplodocus, which probably could have won speed eating contests today. This massive beast measured nearly 100 feet in length and weighed over 33,000 pounds.
"Diplodocus would most likely have fed predominantly on leaves, either biting them off -- much like how we use our incisors -- or raking their teeth along a branch, shearing leaves off the branch," lead author Mark Young told Discovery News.
