Created for the American Museum of Natural History exhibit "The World's Largest Dinosaurs", projected on the side of a 60-foot mamenchisaurus model.

Many plant-eating sauropod dinosaurs sported very long necks—though researchers have debated their purpose. Now, using some fancy mathematics and an analogy with vacuum cleaners, two scientists in the United Kingdom may finally have the answer.

Fossils reveal that some snakes preyed on baby sauropods.

Research suggests the largest dinosaurs, the sauropods, did not stick their necks out in front of them but held their heads high.
