Dinosaur Giants Evolved All-Terrain Bodies

Breaking News

Some of the world's largest dinosaurs headed for the hills and evolved all-terrain bodies to support mountain living, suggests a new study in the journal Paleobiology.

These dinosaurs were titanosaurs, plant eaters that first emerged around 160 million years ago. One of the largest titanosaurs, Argentinosaurus, may have reached lengths of 100 feet.

But palaeontologists Philip Mannion and Paul Upchurch at University College London found that inland and mountain-dwelling titanosaurs had a wider legged stance than coastal dwelling sauropods.
