A National Science Foundation-funded team from Macalester College used a high-powered CT scanner and microscopes to study thin sections of the tibia and other limb bones of the Rapetosaurus. They discovered that these baby behemoths were active, capable of a wider array of maneuvers than adult members of their species and didn't need parental care after hatching.
