Baby Rapetosaurus krausei is compared to neonatal mammals: the dinosaur was only 14 inches tall at the hip, and weighed around 40 kg when it died a few weeks after hatching. This body size is similar to that of some large-bodied mammalian newborns: black rhinoceros calves are 35-45 kg at birth and stand a little taller at the shoulder than baby Rapetosaurus krausei at 25.6 inches (65 cm); African elephants are close to 39 inches (1 m) high at the hip and weigh between 90 and 120 kg at birth; hippo newborns are the closest in both height and mass to the specimen of Rapetosaurus krausei, checking in between 24-45 kg at birth with a shoulder height of 14.6 inches (37 cm).
