Dinosaur locomotion: "Four legs good, two legs better?"
Everyone knows that dinosaurs come in all shapes and sizes. Most don't look like anything that's alive today and some are just plain bizarre. One group that fit this description well are the duck-billed dinosaurs (aka hadrosaurs). Along with the strange appearance (the eponymous duck-bill, peculiar skull ornaments, and long, slender forelimbs) scientists have argued about how they might have moved: Did they walk on four limbs, two limbs, or a combination of both depending on the speed? It has even been suggested that some may have hopped like a kangaroo!
