Evidence from bison fossils has enabled researchers to shape a more accurate timeline for the so-called ‘ice-free corridor’ — a route for Pleistocene human and animal migrations between Beringia in the far north (near Alaska and the Yukon) and the rest of North America. This map shows the location of the ice-free corridor and Paleo-Indian sites. Image credit: Roblespepe / CC BY-SA 3.0. In the 1970s, studies suggested that an ice-free corridor...

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).
