By applying computational engineering methods to model weight and gravitational forces acting on sauropod femurs, researchers found that these massive four-legged dinosaurs were generally able to stay upright while feeding, mating, and defending themselves. Sixty-six million years ago, two types of long-necked, four-legged dinosaurs had an edge over other sauropods because they could readily rise […]
